Participle

In linguistics, a participle is a nonfinite verb form that has some of the characteristics and functions of both verbs and adjectives. More narrowly, participle has been defined as "a word derived from a verb and used as an adjective, as in a laughing face".
"Participle" is a traditional grammatical term from Greek and Latin that is widely used for corresponding verb forms in European languages and analogous forms in Sanskrit and Arabic grammar. In particular, Greek and Latin participles are inflected for gender, number and case, but also conjugated for tense and voice and can take prepositional and adverbial modifiers.
Cross-linguistically, participles may have a range of functions apart from adjectival modification. In European and Indian languages, the past participle is used to form the passive voice. In English, participles are also associated with periphrastic verb forms and are widely used in adverbial clauses. In non-Indo-European languages, 'participle' has been applied to forms that are alternatively regarded as converbs, gerunds, gerundives, transgressives, and nominalised verbs in complement clauses. As a result, 'participles' have come to be associated with a broad variety of syntactic constructions.

Etymology

The word participle comes from classical Latin participium, from particeps 'sharing, participation', because it shares certain properties of verbs, adjectives, and adverbs. The Latin grammatical term is a calque of the Greek grammatical term μετοχή : metochē, 'participation, participle'.
The linguistic term, past participle, was coined circa 1798 based on its participial form, whose morphology equates to the regular form of preterite verbs. The term, present participle, was first used to facilitate grammatical distinctions. Despite the taxonomical use of "past" and "present" as associated with the aforementioned participles, their respective semantic use can entail any tense, regardless of aspect, depending on how they are structurally combined.

Forms

Some languages have extensive participial systems but English has only two participial forms, most commonly termed:

past participle, which is regularly formed with an -ed suffix but has numerous irregular forms ; and
present participle, which is formed with an -ing suffix.

Some grammars further distinguish passive participles as often associated with passive voice versus active participles as often associated with e.g. the progressive tense">progressive aspect">progressive tense, but such linguistic distinctions are neither recognized nor employed on a universal basis.

Types

Participles can be used adjectivally as attributive adjectives. Unlike standard verbs, participles don’t typically have objects or the usual modifiers that verbs have. However, they can be modified by adverbs such as very or slightly. The difference is illustrated by the following examples:

The subject interesting him is Greek history.
Greek history is an interesting subject.
Greek history is a very interesting subject.

In the first sentence, interesting functions transitively in a non-finite sense as a participle that expresses the object him, thereby forming the grammatical equivalent of " interesting him". In the second and third sentences, interesting functions as a prepositive adjective modifying subject. An adverb or a prefix can preface adjectival participles: "a very frightened rabbit", "recently fallen leaves", "uninterested people".
Some languages differentiate adjectival participles and adverbial participles. An adverbial participle plays the role of an adverbial phrase in the sentence in which it appears, whereas an adjectival participle plays the role of an adjective phrase. Such languages include Russian and other Slavic languages, Hungarian, and many Eskimo languages, such as Sirenik, which has a sophisticated participle system. Details can be found in the sections below or in the articles on the grammars of specific languages.
Grammatical descriptions vary in the way these are treated. Some descriptive grammars treat such adverbial and adjectival participles as distinct lexical categories, while others include them both in a single category of participles. Adverbial participles in certain languages may be called converbs, gerunds, or gerundives, or transgressives.

Tense

Participles are often used to form certain grammatical tenses or grammatical aspects. The two types of participle in Modern English are termed present participle and past participle, respectively. The traditional terms are misleading because the participles do not necessarily correspond to tense: the present participle is often associated with the progressive aspect, while the past participle is linked with the perfect aspect or passive voice. See the examples below:

They were just standing there.
By the time you get home, I will have cleaned the house.

The first sentence is in the past tense, but a present participle expresses the progressive aspect. The second sentence is in the future tense, but a past participle is used for the perfect aspect.

Voice

Participles may also be identified with a particular voice: active or passive. Some languages have distinct participles for active and passive uses. In English, the present participle is essentially an active participle, and the past participle has both active and passive uses.
The following examples illustrate those concepts:

I saw John eating his dinner..
The bus has gone..
The window was broken with a rock.
Indo-European languages

Germanic languages

Early English

In Old English, past participles of Germanic strong verbs were marked with a prefix, a West Germanic feature still found in most strong and weak past participles in Dutch and German today, and often by a vowel change in the stem. Those of weak verbs were marked by the ending -d, with or without an epenthetic vowel before it. Modern English past participles derive from these forms.
Old English present participles were marked with an ending in -ende.

Middle English

In Middle English, the form of the present participle varied across regions: -ende, -inde, -and, -inge. The last is the one that became standard, falling together with the suffix -ing used to form verbal nouns. See -ing (etymology).

Modern English

includes two traditional terms for its participles:

The present participle, also sometimes called the active, imperfect, or progressive participle, takes the ending -ing, for example doing, seeing, working, running, breaking, understanding. It is identical in form to the verbal noun and gerund. The term present participle is sometimes used to include the gerund; the term "gerund–participle" is also used to indicate the verb form.
The past participle, also sometimes called the passive or perfect participle, is identical to the past tense form in the case of regular verbs, for example "loaded", "boiled", "mounted", but takes various forms in the case of irregular verbs, such as done, sung, written, broken, understood, put, gone, etc.

In addition, various compound participles can be formed, such as having done, being done, having been doing, having been done.
Details of participle formation can be found under English verbs and List of English irregular verbs.
Participles, or participial phrases formed from them, are used as follows:
1. As an adjective used in an attributive sense:

A broken window
An interesting book
An exciting adventure
The attached files
A fallen tree
Our fallen comrades

Additionally, participles that express an adjectivally attributive meaning can be affixed to form adverbs, such as interestingly and excitedly.
2. In postpositive phrases. These are often regarded as functioning as a reduced relative clause:

A window broken by the wind.
A woman wearing a red hat.
The man standing over there is my uncle.
We are a people clamoring for freedom.

3. In an adverbial phrase. In the following, the subject is understood to be the same as that of the main clause:

Reviewing her bank statement, Ann started to cry.
Having reviewed the bank statement, Ann started to cry.
He shot the man, killing him.
Maintained properly, wooden buildings can last for centuries.

With a different subject, placed before the participle:

He and I having reconciled our differences, the project then proceeded smoothly.

More generally as a part of an adverb:

Broadly speaking, the project was successful.

4. Participles are used to form periphrastic verb tenses:
The present participle forms the progressive aspect with the auxiliary verb be:

Jim was sleeping.

The past participle forms the perfect aspect with the auxiliary verb have:

The chicken has eaten.

5. The past participle is used to form passive voice:

The chicken was eaten.

Such passive participles can appear in an adjectival phrase:

The chicken eaten by the children was contaminated.

Adverbially:

Eaten in this manner, the chicken presents no problem.

And in a nominative absolute construction, with a subject:

The chicken eaten, we returned home.

Note that a past participle that complements a stative verb becomes a passive participle within a passive voice construct.
6. As a gerund. The gerund is traditionally regarded as distinct from the present participle. A gerund can function transitively or intransitively. In both instances, a gerund functions nominatively rather than adjectivally or adverbially—whether as an object or as a subject. Although gerunds and present participles are morphologically identical, their grammatical functions differ substantially.
Sometimes their morphological similarity can create contextual ambiguity, as Noam Chomsky pointed out in his well-known example:

Flying planes can be dangerous.

When the meaning is "The practice of flying a plane is dangerous," flying functions as a gerund; when the danger concerns "Planes that fly" or "Planes when they are flying", flying is being used adjectivally as a participle. For more on the distinctions between these uses of the -ing verb form, see -ing: uses.
For more details on uses of participles and other parts of verbs in English, see Uses of English verb forms, including the sections on the present participle and past participle.
The following table summarises some of the uses of participles in English:

Example	Tense name	Lexical category	Voice
The baked bread		past participle ; adjectival	Passive
Bread baked daily		past participle ; adjectival	Passive
The acting president		present participle ; adjectival	Active
The time remaining		present participle ; adjectival	Active
You look lost	present simple	past participle; adjectival	Passive
You look charming	present simple	present participle; adjectival	Active
You are lost	present simple	past participle; adjectival	Passive
You are losing	present continuous	present participle; aspectual	Active
He has finished	present perfect	past participle; aspectual	Active
He has been finished	present perfect	past participle; aspectual	Passive
He has been finished	present perfect	past participle; adjectival	Passive
He has been finishing	present perfect continuous	present participle; aspectual	Active
She had been run	past perfect	past participle; aspectual	Passive
She had been run	past perfect	past participle; aspectual	Passive
She had been running	past perfect continuous	present participle; aspectual	Active
She had been running ragged	past perfect continuous	past participle; adverbial	Passive
She had been running unwillingly	past perfect continuous	suffixed present participle; adverbial	Passive

Scandinavian languages

In all of the Scandinavian languages the past participle has to agree with the noun to some degree. All of the Scandinavian languages have mandatory agreement with the noun in number. Nynorsk and Swedish have mandatory agreement in both number and gender. Icelandic and Faroese have agreement in number, gender and case. The verb form used for the perfect aspect is generally identical to the nominative neuter singular form of the past participle for all verbs. For the present participle there is no agreement.
Examples in Nynorsk:

Sjølvkøyrande bilar kan vere farlege.
Kyllingen vart eten
Dyret vart ete

The participles are marked in bold. The first example involves a present participle and the two latter examples involves a past participle. All present participles end with an -ande suffix.
In Norwegian, the present participle may be used to form adjectives or adverbs denoting the possibility or convenience of performing the action prescribed by the verb. For example:

Var maten etande?
Utan servo vert bilen fort ukøyrande.

This construction is allowed in Nynorsk, but not in Bokmål, where suffixes like -elig or -bar are used instead.

Latin and Romance languages

Latin

grammar was studied in Europe for hundreds of years, especially the handbook written by the 4th-century teacher Aelius Donatus, and it is from Latin that the name and concept of the participle derives. According to Donatus there are four participles in Latin, as follows:

present participle: present stem + -ns ; e.g. legēns " reading"
perfect participle: supine stem + -us, -a, -um; e.g. lēctus "read "
future participle: supine stem + -ūrus, -ūra, -ūrum; e.g. lēctūrus "going to read", "due to read"
gerundive : e.g. legendus "due to be read", "necessary to be read"

However, many modern Latin grammars treat the gerundive as a separate part of speech.
The perfect participle is usually passive in meaning, and thus mainly formed from transitive verbs, for example frāctus "broken", missus "sent ". However, certain verbs have a perfect participle in an active sense, e.g. profectus "having set out", hortātus "having encouraged", etc. The present and future participles are always active, the gerundive usually passive.
Because a participle is an adjective as well as a verb, just like any other Latin adjective its ending changes according to the noun it describes. So when the noun is masculine, the participle must be masculine; when the noun is in the accusative case, the participle is also in the accusative case; when the noun has plural endings, the participle also has plural endings. Thus a simple participle such as frāctus "broken" can change to frācta, frāctum, frāctī, frāctō and so on, according to its gender, number, and case.
A participle can have a descriptive meaning like an adjective, or a more dynamic meaning like a verb. Thus in the following sentence the participle strīctō "drawn" is better taken as describing an action rather than as describing the sword :

Strīctō gladiō ad dormientem Lucrētiam vēnit.

"With drawn sword he came to the sleeping Lucretia."
The dynamic, verbal meaning is more common, and Latin often uses a participle where English might use a simple verb.
The present participle often describes the circumstances attending the main verb. A typical example is:

Balbus ad mē vēnit currēns.

"Balbus came to me running."
Both the future and the perfect participle can be used with various tenses of the verb esse "to be" to make a compound tense such as the future-in-the-past or the perfect passive:

Eō diē Rōmam ventūrus erat.

"On that day he was going to return to Rome."

Occīsus est ā Thēbānīs.

"He was killed by the Thebans."
The perfect and future participles can also be used, with or without the verb esse "to be", in indirect speech clauses:

locum facile inventūrōs.

"He said that they were easily going to find the place / He said that they would find the place easily."
For uses of the gerundive, see Latin syntax § The gerundive.

French

There are two basic participles:

Present active participle: formed by dropping the -ons of the nous form of the present tense of a verb and then adding ant: marchant "walking", étant "being", ayant "having".
Past participle: formation varies according to verb group: vendu "sold", mis "placed", marché "walked", été "been", and fait "done". The sense of the past participle is passive as an adjective and in most verbal constructions with être, but active in verbal constructions with avoir, in reflexive constructions, and with some intransitive verbs.

Compound participles are possible:

Present perfect participle: ayant appelé "having called", étant mort "being dead"
Passive perfect participle: étant vendu "being sold, having been sold"

Usage:

Present participles are used as qualifiers as in un insecte volant and in some other contexts. They are never used to form tenses.
Past participles are used as qualifiers for nouns: la table cassée ; to form compound tenses such as the perfect Vous avez dit and to form the passive voice: il a été tué.
Spanish

In Spanish, the so-called present or active participle of a verb is traditionally formed with one of the suffixes -ante, -ente or -iente, but modern grammar does not consider it a true participle, as such forms usually have the meaning of simple adjectives or nouns: e.g. amante "loving" or "lover", viviente "living" or "live".
The past participle is regularly formed with one of the suffixes -ado or -ido, or -cho. The past participle is used generally as an adjective referring to a finished action, in which case its ending changes according to gender and number. At other times is used to form compound tenses: the present perfect, past perfect, and the future perfect, in which case it is indeclinable. Some examples:
As an adjective :

las cartas escritas "the written letters"

To form compound tenses:

Ha escrito una carta. "She has written a letter."
Había escrito una carta. "She had written a letter."
Habrá escrito una carta. "She will have written a letter."
Hellenic languages

Ancient Greek

The Ancient Greek participle shares in the properties of adjectives and verbs. Like an adjective, it changes form for gender, case, and number. Like a verb, it has tense and voice, is modified by adverbs, and can take verb arguments, including an object. Participles are quite numerous in Ancient Greek: a non-defective verb has as many as ten participles.
There is a form of the participle for every combination of aspect and voice. All participles are based on their finite forms. Here are the masculine nominative singular forms for a thematic and an athematic verb:
Like an adjective, it can modify a noun, and can be used to embed one thought into another.
In the example, the participial phrase τὸν εὖ στρατηγήσοντα tòn eû stratēgḗsonta, literally "the one going to be a good general", is used to embed the idea εὖ στρατηγήσει eû stratēgḗsei "he will be a good general" within the main verb.
The participle is very widely used in Ancient Greek, especially in prose.

Indo-Aryan languages

Hindi and Urdu

There are two types of participles in Hindi and Urdu, aspectual participles which mark the aspect and non-aspectual participles which do not mark verbal aspect. The table below mentions the different participles present in Hindustani, ɸ denotes the verb root. The aspectual participles can take a few other copulas after them besides the verb honā "to be". Those copular verbs are rêhna "to stay", ānā "to come", jānā "to go".

Sanskrit

Much like Ancient Greek, Sanskrit has a wide array of participles.

Celtic languages

Cornish

In Cornish, an equivalent present participle construction to English is formed by using ow with a verbal noun, e.g. Yma an den ow hwerthin, and den ow hwerthin. Like Breton but unlike Welsh, Cornish also has verbal adjectives which are used similarly to English past participles, e.g. dehen molys, from the verbal noun mola "to clot".

Welsh

In Welsh, the effect of a participle in the active voice is constructed by yn followed by the verb-noun and wedi followed by the verb-noun. There is no mutation in either case. In the passive voice, participles are usually replaced by a compound phrase such as wedi cael ei/eu in modern Welsh and by the impersonal form in literary Welsh.

Slavic languages

Polish

The Polish word for participle is imiesłów. There are four types of imiesłowy in two classes:
Adjectival participle :

active adjectival participle : robiący – "doing", "one who does"
passive adjectival participle : robiony – "being done"

Adverbial participle :

present adverbial participle : robiąc – "doing", "while doing"
perfect adverbial participle : zrobiwszy – "having done"

Due to the distinction between adjectival and adverbial participles, in Polish it is practically impossible to make a dangling participle in the classical English meaning of the term. For instance, in the sentence:

I found them hiding in the closet.

it is unclear whether "I" or "they" were hiding in the closet. In Polish there is a clear distinction:

Znalazłem ich, chowając się w szafie. – chowając is a present adverbial participle agreeing grammatically with the subject
Znalazłem ich chowających się w szafie. – chowających is an active adjectival participle agreeing grammatically with the object
Russian

Verb: слышать

Present active: слышащий "hearing", "who hears"
Present passive: слышимый "being heard", "that is heard", "audible"
Past active: слышавший "who heard", "who was hearing"
Past passive: слышанный "that was heard", "that was being heard"
Adverbial present active: слыша " hearing"
Adverbial past active: слышав " hearing"

Verb: услышать

Past active: услышавший "who has heard"
Past passive: услышанный "that has been heard", "who has been heard"
Adverbial past active: услышав "having heard", "after hearing"

Future participles formed from perfective verbs are not considered a part of standard language.

Bulgarian

Participles are adjectives formed from verbs. There are various kinds:
Verb: правя :

Present active: правещ
Past active aorist: правил
Past active imperfect: правел
Past passive: правен
Adverbial present active: правейки

Verb: направя :

Past active aorist: направил
Past active imperfect: направел
Past passive: направен
Macedonian

Macedonian has completely lost or transformed the participles of Common Slavic, unlike the other Slavic languages. The following points may be noted:

present active participle: this has transformed into a verbal adverb;
present passive participle: there are some isolated cases or remnants of the present passive participle, such as the word лаком ;
past active participle: there is only one remnant of the past active participle, which is the word бивш . However, this word is often replaced with the word поранешен ;
past passive participle: this has been transformed into a verbal adjective ;
resultative participle: this has transformed into a verbal l-form. It is not a participle since it does not function attributively.
Baltic languages

Lithuanian

Among Indo-European languages, the Lithuanian language is unique for having 14 different participial forms of the verb, which can be grouped into five when accounting for inflection by tense. Some of these are also inflected by gender and case. For example, the verb eiti has the active participle forms einąs/einantis, ėjęs, eisiąs, eidavęs, the passive participle forms einamas, eitas, eisimas, the adverbial participles einant, ėjus, eisiant, eidavus, the semi-participle eidamas and the participle of necessity eitinas. The active and passive participles and the semi-participles are inflected by gender, and the active, passive and necessity participles are inflected by case.

Semitic languages

Arabic

The Arabic verb has two participles: an active participle and a passive participle, and the form of the participle is predictable by inspection of the dictionary form of the verb. These participles are inflected for gender, number and case, but not person. Arabic participles are employed syntactically in a variety of ways: as nouns, as adjectives or even as verbs. Their uses vary across varieties of Arabic. In general the active participle describes a property of the syntactic subject of the verb from which it derives, whilst the passive participles describes the object. For example, from the verb كتب kataba, the active participle is kātib كاتب and the passive participle is maktūb مكتوب. Roughly these translate to "writing" and "written" respectively. However, they have different, derived lexical uses. كاتب kātib is further lexicalized as "writer", "author" and مكتوب maktūb as "letter".
In Classical Arabic, the participles do not participate in verbal constructions with auxiliaries the same way as their English counterparts and rarely take on a verbal meaning in a sentence. In certain dialects of Arabic, however, it is much more common for the participles, especially the active participle, to have verbal force in the sentence. For example, in dialects of the Levant, the active participle is a structure that describes the state of the syntactic subject after the action of the verb from which it derives has taken place. ʼĀkil, the active participle of ʼakala, describes one's state after having eaten something. Therefore, it can be used in analogous way to the English present perfect. Other verbs, such as rāḥa راح give a participle, which has a progressive meaning. The exact tense or continuity of the participles is, therefore, determined by the nature of the specific verb and the syntactic/semantic context of the utterance. What ties them all together is that they describe the subject of the verb from which they derive. The passive participles in certain dialects can be used as a sort of passive voice, but more often than not, they are used in their various lexicalized senses as adjectives or nouns.

Hebrew

Like Arabic, Hebrew has two types of participles : an active participle and a passive participle. These participles are inflected for gender and number. The active participle takes a variety of syntactic roles, such as a verb in present tense, a noun, and an adjective.
Hebrew has a syntactic construction of the verb "to be" in the past tense, and the active participle that cognates to the past progressive tense in English. For example, the word עבדתי avádti means "I worked", and הייתי עובד hayíti ovéd means "I was working". Another use of this syntactic structure is equivalent to "used to" in English. For example, דויד בילדותו היה גר בארצות הברית davíd b'yaldutó hayá gar b'arcót habrít.

Finno-Ugric languages

Finnish

uses six participles to convey different meanings. Below is a table displaying the declension of the participles of the verb tappaa.

	Active	Passive
Present	tappava	tapettava
Past	tappanut	tapettu

The participles work in the following way:

tappava	Present active participle: Conveys an ongoing action. Used to omit the use of the relative pronoun who, which or that. Tappava means "killing" as in "killing machine". In other words, machine that kills. It can also work as the subject of the sentence. In other words, tappava can mean "the one who kills" or "he who kills". Tappava on... = He who kills is...
tapettava	Present passive participle: Conveys possibility and obligation. Possibility as in -able and obligation as in something that has to be killed. Tapettava mies can mean both "the killable man" and "the man who has to be killed".
tappanut	Past active participle: Used with the verb olla to construct the perfect and the past perfect tenses. In English the verb "to have" is used to form the perfect and past perfect tense, in Finnish the verb "to be" is used instead. Just like the present active participle, it can also be used as the subject in a sentence, except it conveys the meaning in the past tense. In other words, tappanut can mean "the one who killed" or "he who killed". Tappanut on... = He who killed is...
tapettu	Past passive participle: A concluded action. Tapettu mies = the killed man.
tappama-	Agent participle: Always used with a possessive suffix. It is used to convey the meaning of the word "by" in English, since there is no word for "by" in Finnish. Hänen tappamansa mies = The man killed by him. The tense of the translation depends on the context.
tappamaton	Negative participle: Used to convey impossibility and undoneness. Tappamaton mies means both "unkillable man" and "man not killed".

Each of the participles can be used as adjectives and so some of them can be turned into nouns.

Finnish	tappava	tapettava	tappamaton
English	killing	killable	unkillable or not killed
Finnish	tappavuus	tapettavuus	tappamattomuus
English	killingness	killability	unkillability or lack of killing

Hungarian

uses adjectival and adverbial participles.
Adjectival participles can be one of these three types:

Present : olvas – olvasó, él – élő
Past : zár – zárt
Future : olvas – olvasandó, fizet – fizetendő

Adverbial participles can be:

Imperfect: siet – sietve
Perfect: bemegy – bemenvén

In Hungarian grammar, the infinitive is also considered a kind of participle, the noun participle.

Turkic languages

Turkish

Participles are called sıfat-fiil or ortaç in Turkish.
Turkish participles consist of a verb stem and a suffix. Some participles may be conjugated, but some may not. Participles always precede the noun they are defining, unlike in English.
Participle suffixes, like many other suffixes in Turkish, change according to the vowel harmony and sandhi.
There are eight types of participle suffixes; -en, -esi, -mez, -ar, -di, -ecek and -miş
An easy way to remember those is a mnemonic taught in Turkish schools: Anası mezar dikecekmiş, which has every type of the suffixes, and is still a coherent sentence, translated as "his/her mother is allegedly going to plant a grave".

Eskimo–Aleut languages

Sirenik

, an extinct Eskimo–Aleut language, had separate sets of adverbial participles and adjectival participles. Unlike in English, adverbial participles were conjugated to reflect the person and number of their implicit subjects; hence, an adverbial participle could replace a clause in the English sentence "If I were a marksman, I would kill walruses" since the subject was implied by the conjugation.

Constructed languages

Esperanto

has six different participle conjugations; active and passive for past, present and future. The participles are formed as follows:

	Past	Present	Future
Active	-inta	-anta	-onta
Passive	-ita	-ata	-ota

For example, a falonta botelo is a bottle that will fall or is about to fall. A falanta botelo is one that is falling through the air. After it hits the floor, it is a falinta botelo. These examples use the active participles, but the usage of the passive participles is similar. A cake that is going to be divided is a dividota kuko. When it is in the process of being divided, it is a dividata kuko. Having been cut, it is now a dividita kuko.
These participles can be used in conjunction with the verb to be, esti, forming 18 compound tenses. However, this soon becomes complicated and often unnecessary, and is only frequently used when rigorous translation of English is required. An example of this would be la knabo estos instruita, or, 'the boy will have been taught'. This example sentence is then in the future anterior.
When the suffix -o is used, instead of -a, then the participle refers to a person. A manĝanto is someone who is eating. A manĝinto is someone who ate. A manĝonto is someone who will eat. Also, a manĝito is someone who was eaten, a manĝato is someone who is being eaten, and a manĝoto is someone who will be eaten.
These rules hold true for all transitive verbs. Since copular and intransitive verbs do not have passive voice, their participle forms can only be active.
An informal and unofficial addition to these six are the participles for conditional forms, which use -unt- and -ut-. For example, parolunto refers to someone who would speak, and a leguta libro is a book that would be read. These unofficial participle forms are however very rarely used in practice.
