1. X-bar theory

   In linguistics, X-bar theory is a model of phrase-structure grammar and a theory of syntactic category formation that was first proposed by Noam Chomsky in 1970 and further developed by Ray Jackendoff (1974, 1977a, 1977b), along the lines of the theory of generative grammar put forth in the 1950s by Chomsky. It attempts to capture the structure of phrasal categories with a single uniform structure called the X-bar schema, basing itself on the assumption that any phrase in natural language is an XP (X phrase) that is headed by a given syntactic category X. It played a significant role in resolving issues that phrase structure rules had, representative of which is the proliferation of grammatical rules, which is against the thesis of generative grammar. X-bar theory was incorporated into both transformational and nontransformational theories of syntax, including government and binding theory (GB), generalized phrase structure grammar (GPSG), lexical-functional grammar (LFG), and head-driven phrase structure grammar (HPSG). Although recent work in the minimalist program has largely abandoned X-bar schemata in favor of bare phrase structure approaches, the theory's central assumptions are still valid in different forms and terms in many theories of minimalist syntax.

1. x-bar theory

   X-bar theory is a linguistic framework that describes the internal structure of phrases in natural language, particularly in terms of their hierarchical organization. It proposes that all phrases consist of a head, which is typically a noun or a verb, surrounded by optional specifier and adjunct elements. The theory suggests that these constituents are organized in a hierarchical manner, with the head at the center (X-bar) and the other elements branching out from it. X-bar theory aims to explain the syntactic structure and ordering of various elements within phrases, contributing to our understanding of sentence formation and grammatical patterns in language.

1. X-bar theory

   X-bar theory is a component of linguistic theory which attempts to identify syntactic features presumably common to all those human languages that fit in a presupposed framework. It claims that among their phrasal categories, all those languages share certain structural similarities, including one known as the "X-bar", which does not appear in traditional phrase structure rules for English or other natural languages. X-bar theory was first proposed by Noam Chomsky and further developed by Ray Jackendoff. An X-bar theoretic understanding of sentence structure is possible in a constituency-based grammar only; it is not possible in a dependency-based grammar. The letter X is used to signify an arbitrary lexical category; when analyzing a specific utterance, specific categories are assigned. Thus, the X may become an N for noun, a V for verb, an A for adjective, or a P for preposition. The term X-bar is derived from the notation representing this structure. Certain structures are represented by X. Because this is difficult to typeset, this is often written as X′, using the prime symbol. In English, however, this is still read as "X bar". The notation XP stands for X Phrase, and is equivalent to X-bar-bar, written X″, usually read aloud as X double bar.
