Theory of language is a topic in philosophy of language and theoretical linguistics. [1] It has the goal of answering the questions "What is language?"; [2] [3] "Why do languages have the properties they do?"; [4] or "What is the origin of language?". In addition to these fundamental questions, the theory of language also seeks to understand ...
The Chomsky hierarchy in the fields of formal language theory, computer science, and linguistics, is a containment hierarchy of classes of formal grammars. A formal grammar describes how to form strings from a language's vocabulary (or alphabet) that are valid according to the language's syntax. The linguist Noam Chomsky theorized that four ...
The usage-based linguistics is a linguistics approach within a broader functional / cognitive framework, that emerged since the late 1980s, and that assumes a profound relation between linguistic structure and usage. [1] It challenges the dominant focus, in 20th century linguistics (and in particular in formalism - generativism), on considering ...
Theoretical linguistics is a term in linguistics that, [1] like the related term general linguistics, [2] can be understood in different ways. Both can be taken as a reference to the theory of language, or the branch of linguistics that inquires into the nature of language and seeks to answer fundamental questions as to what language is, or what the common ground of all languages is.

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 ...
Chomsky normal form. Not to be confused with conjunctive normal form. In formal language theory, a context-free grammar, G, is said to be in Chomsky normal form (first described by Noam Chomsky) [ 1 ] if all of its production rules are of the form: [ 2 ][ 3 ] A → BC, or. A → a, or.
In formal language theory, the Chomsky–Schützenberger representation theorem is a theorem derived by Noam Chomsky and Marcel-Paul Schützenberger in 1959 [1] about representing a given context-free language in terms of two simpler languages. These two simpler languages, namely a regular language and a Dyck language, are combined by means of ...
Linguistic relativity and the color naming debate. The concept of linguistic relativity concerns the relationship between language and thought, specifically whether language influences thought, and, if so, how. This question has led to research in multiple disciplines—including anthropology, cognitive science, linguistics, and philosophy.
