Glossematics
In linguistics, glossematics is a structuralist theory proposed by Louis Hjelmslev and Hans Jørgen Uldall. It defines the glosseme as the most basic unit of language.
Hjelmslev and Uldall eventually went separate ways with their respective approaches. Hjelmslev's theory, most notably, is an early mathematical methodology for the analysis of language which was subsequently incorporated into the analytical foundation of current models of functional–structural grammar such as Danish Functional Grammar, Functional Discourse Grammar and Systemic Functional Linguistics. Hjelmslev's theory likewise remains fundamental for modern semiotics.
Meaning
Glossematics defines the glosseme as the smallest irreducible unit of both the content and expression planes of language; in the expression plane, the glosseme is nearly identical to the phoneme. In the content plane, it is the smallest unit of meaning which underlies a concept. A ewe, for example, consists of the taxemes sheep and female which may eventually be divided into even smaller units – glossemes – of meaning. The analysis is gradually expanded to the study of functions, more commonly known as dependencies, between elements on the level of discourse, and between meaning and form in the linguistic system.The term glosseme was coined by Louis Hjelmslev and Hans Jørgen Uldall in the 1930s. It derives from the Greek word Tongue and the -eme suffix. A similar idea was used by Leonard Bloomfield in describing his system of basic linguistic units, tagmemes, although glossematics is more far-reaching in each direction.
Hjelmslev's theory of language
Glossematics is an expansion of Saussure's concept of language as a dual system of meaning and form. This is in contrast to a contemporary American tendency of placing semantics outside the core of linguistics. Hjelmslev was also influenced by the Prague Linguistic Circle to the extent that he considered full texts as the material for analysis rather than ‘utterances' as was commonplace in American structuralism. Diverging from both American and European linguists, though, Hjelmslev considered language not as a social fact but as a computational system which underlies all sciences.The ultimate goal of the linguist is to gain a more perfect understanding of the whole through a thorough study of the structure of the constituent parts. To the greatest extent possible, glossematics seeks to construct a non-historical, non-sociological and non-psychological model based on language-specific principles and minimal reliance on factors external to the system. The linguist's task, analysing texts or corpora of different languages, aims to establish a universal model of the inner workings of language by comparing the underlying meta-structures of a given language to others. Rather than separate fields of study, Hjelmslev regarded phonology, morphology, syntax, lexicology and semantics as part of the same apparatus.
By ‘phonetics' and ‘semantics' Hjelmslev means unorganised sound and meaning. Instead, a linguist must study expression and content, the systematised organisation of form and meaning of a given language which is to be deduced from the research material. As manifested by subsequent models of structural grammar, but also to an extent by generative grammar, units of a given level are collected into inventories. Glossematics is then meant to become a device which can correctly predict all grammatical sentences of any language." Hjelmslev's idea later came to be associated with Noam Chomsky who used a modification of it made by his PhD supervisor Zellig Harris. Hjelmslev's influence extends to semiotics and to the systemic and Danish grammatical models of functional linguistics.
