Colexification
In semantics and lexical typology, colexification is the ability for a language to express different meanings with the same word.
When a language colexifies several concepts, this is generally understood as a sign that these concepts are semantically related. Research in lexical typology has thus been using colexification as a tool to measure semantic similarity between concepts.
Definition
Colexification describes the case of different meanings being expressed by the same word in a language. For example, the two senses which are distinguished in English as people and village are colexified in Spanish, which uses in both cases.Colexification is meant as a neutral descriptive term that avoids distinguishing between vagueness, polysemy, and homonymy. Some cases of colexification are common across the world ; others are typical of certain linguistic and cultural areas.
The opposite of "-lexify" is "-lexify", i.e. 'express two meanings using different lexical forms'. Thus, Russian colexifies 'arm' and 'hand' using the single word, but Spanish dislexifies these two meanings using two distinct words, respectively v..

Use in linguistic studies
The term was coined by the linguist Alexandre François in his [|2008 article] "Semantic maps and the typology of colexification". This article illustrated the notion with various examples, including the semantic domains of,,. The latter notion is at the source of a colexification network that is attested in several languages, linking together such senses as 'breath', 'life', 'soul', 'spirit', 'ghost'...: Sanskrit ātmán; Ancient Greek, ; Latin, ; Arabic rūḥ, etc. François built on that example to propose a method for constructing lexical semantic maps.Several studies have taken up the concept of colexification and applied it to different semantic domains and various language families.
Colexification is also the object of a dedicated database, known as "Database of Cross-Linguistic Colexifications". Based on data from more than 2400 language varieties of the world, the database makes it possible to check the typological frequency of individual instances of colexification, and to visualize semantic networks based on empirical data from the world's languages.
