Right-branching Language
In linguistics, branching refers to the shape of the parse trees that represent the structure of sentences. Assuming that the language is being written or transcribed from left to right, parse trees that grow down and to the right are ''right-branching'', and parse trees that grow down and to the left are ''left-branching''. The direction of branching reflects the position of heads in phrases, and in this regard, right-branching structures are ''head-initial'', whereas left-branching structures are ''head-final''. English has both right-branching (head-initial) and left-branching (head-final) structures, although it is more right-branching than left-branching. Some languages such as Japanese and Turkish are almost fully left-branching (head-final). Some languages are mostly right-branching (head-initial). Examples Languages typically construct phrases with a head word (or nucleus) and zero or more ''dependents'' (modifiers). The following phrases show the phrase heads in bold. ...

Linguistics
Linguistics is the scientific study of language. The areas of linguistic analysis are syntax (rules governing the structure of sentences), semantics (meaning), Morphology (linguistics), morphology (structure of words), phonetics (speech sounds and equivalent gestures in sign languages), phonology (the abstract sound system of a particular language, and analogous systems of sign languages), and pragmatics (how the context of use contributes to meaning). Subdisciplines such as biolinguistics (the study of the biological variables and evolution of language) and psycholinguistics (the study of psychological factors in human language) bridge many of these divisions. Linguistics encompasses Outline of linguistics, many branches and subfields that span both theoretical and practical applications. Theoretical linguistics is concerned with understanding the universal grammar, universal and Philosophy of language#Nature of language, fundamental nature of language and developing a general ...

X-bar Theory
In linguistics, X-bar theory is a model of phrase structure and a theory of syntactic category formation that proposes a universal schema for how phrases are organized. It suggests that all phrases share a common underlying structure, regardless of their specific category (noun phrase, verb phrase, etc.). This structure, known as the X-bar schema, is based on the idea that every phrase (XP, X phrase) has a Head (linguistics), head, which determines the type (syntactic category) of the phrase (X). The theory was first proposed by Noam Chomsky in 1970Chomsky, Noam (1970). Remarks on Nominalization. In: R. Jacobs and P. Rosenbaum (eds.) ''Reading in English Transformational Grammar'', 184–221.

Spanish Language
Spanish () or Castilian () is a Romance languages, Romance language of the Indo-European languages, Indo-European language family that evolved from the Vulgar Latin spoken on the Iberian Peninsula of Europe. Today, it is a world language, global language with 483 million native speakers, mainly in the Americas and Spain, and about 558 million speakers total, including second-language speakers. Spanish is the official language of List of countries where Spanish is an official language, 20 countries, as well as one of the Official languages of the United Nations, six official languages of the United Nations. Spanish is the world's list of languages by number of native speakers, second-most spoken native language after Mandarin Chinese; the world's list of languages by total number of speakers, fourth-most spoken language overall after English language, English, Mandarin Chinese, and Hindustani language, Hindustani (Hindi-Urdu); and the world's most widely spoken Romance language ...

Shifting (syntax)
In syntax, shifting occurs when two or more constituent (linguistics), constituents appearing on the same side of their common head (linguistics), head exchange positions in a sense to obtain non-canonical order. The most widely acknowledged type of shifting is heavy NP shift, but shifting involving a heavy NP is just one manifestation of the shifting mechanism. Shifting occurs in most if not all European languages, and it may in fact be possible in all natural languages including sign language, sign languages. Shifting is not inversion (linguistics), inversion, and inversion is not shifting, but the two mechanisms are similar insofar as they are both present in languages like English that have relatively strict word order. The theoretical analysis of shifting varies in part depending on the theory of sentence structure that one adopts. If one assumes relatively flat structures, shifting does not result in a discontinuity (linguistics), discontinuity. Shifting is often motivated by t ...

Inversion (linguistics)
In linguistics, inversion is any of several grammatical constructions where two expressions switch their typical or expected order of appearance, that is, they invert. There are several types of subject-verb inversion in English: ''locative inversion'', ''directive inversion'', ''copular inversion'', and ''quotative inversion''. The most frequent type of inversion in English language, English is subject–auxiliary inversion in which an English auxiliaries, auxiliary verb changes places with its subject (grammar), subject; it often occurs in questions, such as ''Are you coming?'', with the subject ''you'' being switched with the auxiliary ''are''. In many other languages, especially those with a freer word order than that of English, inversion can take place with a variety of verbs (not just auxiliaries) and with other syntactic categories as well. When a layered phrase structure grammar, constituency-based analysis of sentence structure is used, inversion often results in the dis ...

Discontinuity (linguistics)
In linguistics, a discontinuity occurs when a given word or phrase is separated from another word or phrase that it modifies in such a manner that a direct connection cannot be established between the two without incurring crossing lines in the Parse tree, tree structure. The terminology that is employed to denote discontinuities varies depending on the theory of syntax at hand. The terms ''discontinuous constituent'', ''displacement'', ''long distance dependency'', ''unbounded dependency'', and ''projectivity violation'' are largely synonymous with the term ''discontinuity''. There are various types of discontinuities, the most prominent and widely studied of these being topicalization, wh-fronting, scrambling (linguistics), scrambling, and extraposition. Natural languages vary with respect to the types of discontinuities that they permit. The fixed word order of English allows for relatively few discontinuities compared to, for instance, the Slavic languages, which are much more p ...

Word Grammar
Word Grammar is a theory of linguistics, developed by Richard Hudson since the 1980s. It started as a model of syntax, whose most distinctive characteristic is its use of dependency grammar, an approach to syntax in which the sentence's structure is almost entirely contained in the information about individual words, and syntax is seen as consisting primarily of principles for combining words. The central syntactic relation is that of dependency between words; constituent structure is not recognized except in the special case of coordinate structures. However an even more important claim of Word Grammar is that statements about words and their properties form a complex network of propositions. More recent work on Word Grammar cites neurocognitive linguistics as a source of inspiration for the idea that language is nothing but a network. One of the attractions of the network view is the possibility of analysing language in the same way as other kinds of knowledge, given that knowled ...

Head-Driven Phrase Structure Grammar
Head-driven phrase structure grammar (HPSG) is a highly lexicalized, constraint-based grammar developed by Carl Pollard and Ivan Sag. It is a type of phrase structure grammar, as opposed to a dependency grammar, and it is the immediate successor to generalized phrase structure grammar. HPSG draws from other fields such as computer science (type system, data type theory and knowledge representation) and uses Ferdinand de Saussure's notion of the sign (linguistics), sign. It uses a uniform formalism and is organized in a modular way which makes it attractive for natural language processing. An HPSG includes principles and grammar rules and lexicon entries which are normally not considered to belong to a grammar. The formalism is based on lexicalism. This means that the lexicon is more than just a list of entries; it is in itself richly structured. Individual entries are marked with types. Types form a hierarchy. Early versions of the grammar were very lexicalized with few grammatica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transformational Grammar
In linguistics, transformational grammar (TG) or transformational-generative grammar (TGG) was the earliest model of grammar proposed within the research tradition of generative grammar. Like current generative theories, it treated grammar as a system of formal rules that generate all and only grammatical sentences of a given language. What was distinctive about transformational grammar was that it posited transformation rules that mapped a sentence's deep structure to its pronounced form. For example, in many variants of transformational grammar, the English active voice sentence "Emma saw Daisy" and its passive counterpart "Daisy was seen by Emma" share a common deep structure generated by phrase structure rules, differing only in that the latter's structure is modified by a passivization transformation rule. Basic mechanisms Transformational grammar was a species of generative grammar and shared many of its goals and postulations, including the notion of linguistics as a ...

Lexical Functional Grammar
Lexical functional grammar (LFG) is a constraint-based grammar framework in theoretical linguistics. It posits several parallel levels of syntactic structure, including a phrase structure grammar representation of word order and constituency, and a representation of grammatical functions such as subject and object, similar to dependency grammar. The development of the theory was initiated by Joan Bresnan and Ronald Kaplan in the 1970s, in reaction to the theory of transformational grammar which was current in the late 1970s. It mainly focuses on syntax, including its relation with morphology and semantics. There has been little LFG work on phonology (although ideas from optimality theory have recently been popular in LFG research). Some recent work combines LFG with Distributed Morphology in Lexical-Realizational Functional Grammar.Ash Asudeh, Paul B. Melchin & Daniel Siddiqi (2021).
