Exocentric Structure
In theoretical linguistics, a distinction is made between endocentric and exocentric constructions. A grammatical construction (for instance, a phrase or compound) is said to be ''endocentric'' if it fulfils the same linguistic function as one of its parts, and ''exocentric'' if it does not. The distinction reaches back at least to Bloomfield's work of the 1930s, who based it on terms by Pāṇini and Patañjali in Sanskrit grammar. Such a distinction is possible only in phrase structure grammars (constituency grammars), since in dependency grammars all constructions are necessarily endocentric. Endocentric construction An endocentric construction consists of an obligatory head and one or more dependents, whose presence serves to modify the meaning of the head. For example: # sub>NP [A big[N house">lt;sub>A<_sub>_big.html" ;"title="sub>NP [A big">sub>NP [A big[N house #[VP [V sing] [N songs #[AP [Adv very] [A long These phrases are indisputably endocentric. They are end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endocentric Environment
In the field of user interfaces, an endocentric environment refers to a virtual reality or some other immersive environment which is introduced directly into the user's senses (for example by using VR goggles). Systems which display a virtual reality indirectly to the user (for example by placing the viewer in a room made up entirely of rear projection screens) do not qualify. See also * Exocentric environment In the field of user interfaces, an exocentric environment refers to a virtual reality or some other immersive environment which completely encompasses the user, e.g. by placing the viewer in a room made up entirely of rear projection screens.

Subject (grammar)
The subject in a simple English sentence such as ''John runs'', ''John is a teacher'', or ''John drives a car'', is the person or thing about whom the statement is made, in this case ''John''. Traditionally the subject is the word or phrase which controls the verb in the clause, that is to say with which the verb agrees (''John is'' but ''John and Mary are''). If there is no verb, as in ''John what an idiot!'', or if the verb has a different subject, as in ''John I can't stand him!'', then 'John' is not considered to be the grammatical subject, but can be described as the ''topic'' of the sentence. While these definitions apply to simple English sentences, defining the subject is more difficult in more complex sentences and in languages other than English. For example, in the sentence ''It is difficult to learn French'', the subject seems to be the word ''it'', and yet arguably the real subject (the thing that is difficult) is ''to learn French''. A sentence such as ''It was J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bahuvrihi
A ''bahuvrihi'' compound (from sa, बहुव्रीहि, tr=bahuvrīhi, lit=much rice/having much rice, originally referring to fertile land but later denoting the quality of being wealthy or rich) is a type of compound word that denotes a referent by specifying a certain characteristic or quality the referent possesses. A bahuvrihi is exocentric, so that the compound is not a hyponym of its head. For instance, a sabretooth ('' smil-odon'') is neither a sabre nor a tooth, but a feline with sabre-like teeth. In Sanskrit bahuvrihis, the last constituent is a noun—more strictly, a nominal stem—while the whole compound is an adjective. In Vedic Sanskrit the accent is regularly on the first member ( ' "a king's son", but bahuvrihi ' "having kings as sons" ( lit. king-sons), viz. ', m., "father of kings", ', f., "mother of kings"), with the exception of a number of non-nominal prefixes such as the privative a; the word ' is itself likewise an exception to this rule. Bahu ...

Compound (linguistics)
In linguistics, a compound is a lexeme (less precisely, a word or sign) that consists of more than one stem. Compounding, composition or nominal composition is the process of word formation that creates compound lexemes. Compounding occurs when two or more words or signs are joined to make a longer word or sign. A compound that uses a space rather than a hyphen or concatenation is called an open compound or a spaced compound; the alternative is a closed compound. The meaning of the compound may be similar to or different from the meaning of its components in isolation. The component stems of a compound may be of the same part of speech—as in the case of the English word ''footpath'', composed of the two nouns ''foot'' and ''path''—or they may belong to different parts of speech, as in the case of the English word ''blackbird'', composed of the adjective ''black'' and the noun ''bird''. With very few exceptions, English compound words are stressed on their first component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (linguistics)
In linguistics, morphology () is the study of words, how they are formed, and their relationship to other words in the same language. It analyzes the structure of words and parts of words such as stems, root words, prefixes, and suffixes. Morphology also looks at parts of speech, intonation and stress, and the ways context can change a word's pronunciation and meaning. Morphology differs from morphological typology, which is the classification of languages based on their use of words, and lexicology, which is the study of words and how they make up a language's vocabulary. While words, along with clitics, are generally accepted as being the smallest units of syntax, in most languages, if not all, many words can be related to other words by rules that collectively describe the grammar for that language. For example, English speakers recognize that the words ''dog'' and ''dogs'' are closely related, differentiated only by the plurality morpheme "-s", only found bound to noun ...

Warlpiri Language
The Warlpiri ( or ) ( wbp, Warlpiri > waɭbɪ̆ˌɻi language is spoken by about 3,000 of the Warlpiri people from the Tanami Desert, northwest of Alice Springs, Central Australia. It is one of the Ngarrkic languages of the large Pama–Nyungan family and is one of the largest Aboriginal languages in Australia in terms of number of speakers. One of the most well-known terms for The Dreaming (an Aboriginal spiritual belief), ''Jukurrpa'', derives from Warlpiri. Warnayaka (Wanayaga, Woneiga), Wawulya (Ngardilpa), and Ngalia are regarded as probable dialects of Warlpiri on the AUSTLANG database, although with potentially no data; while Ngardilypa is confirmed. Phonology In the following tables of the Warlpiri sound system, symbols in boldface give the practical alphabet used by the Warlpiri community. Phonemic values in IPA are shown in /slashes/ and phonetic values in quare brackets Vowels Warlpiri has a standard three-vowel system, similar to that of Classical Arab ...

Non-configurational Language
In generative grammar, non-configurational languages are languages characterized by a flat phrase structure, which allows syntactically discontinuous expressions, and a relatively free word order. History of the concept of "non-configurationality" The concept of non-configurationality was developed by grammarians working within Noam Chomsky's generative framework. Some of these linguists observed that the Syntactic Universals proposed by Chomsky and which required a rigid phrase structure was challenged by the syntax of some of the world's languages that had a much less rigid syntax than that of the languages on which Chomsky had based his studies. The concept was invented by Ken Hale who described the syntax of Warlpiri as being non-configurational. However, the first to publish a description of non-configurationality was Chomsky himself in his 1981 lectures on Government and Binding, in which he referred to an unpublished paper by Hale. Chomsky made it a goal of the Government a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grammar Frameworks
In linguistics, the grammar of a natural language is its set of structural constraints on speakers' or writers' composition of clauses, phrases, and words. The term can also refer to the study of such constraints, a field that includes domains such as phonology, morphology, and syntax, often complemented by phonetics, semantics, and pragmatics. There are currently two different approaches to the study of grammar: traditional grammar and theoretical grammar. Fluent speakers of a language variety or ''lect'' have effectively internalized these constraints, the vast majority of which – at least in the case of one's native language(s) – are acquired not by conscious study or instruction but by hearing other speakers. Much of this internalization occurs during early childhood; learning a language later in life usually involves more explicit instruction. In this view, grammar is understood as the cognitive information underlying a specific instance of language production. Th ...

Constraint-based Grammar
Model-theoretic grammars, also known as constraint-based grammars, contrast with generative grammars in the way they define sets of sentences: they state constraints on syntactic structure rather than providing operations for generating syntactic objects. A generative grammar provides a set of operations such as rewriting, insertion, deletion, movement, or combination, and is interpreted as a definition of the set of all and only the objects that these operations are capable of producing through iterative application. A model-theoretic grammar simply states a set of conditions that an object must meet, and can be regarded as defining the set of all and only the structures of a certain sort that satisfy all of the constraints. The approach applies the mathematical techniques of model theory to the task of syntactic description: a grammar is a theory in the logician's sense (a consistent set of statements) and the well-formed structures are the models that satisfy the theory.

Inflectional Phrase
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 1970Chomsky, Noam (1970). Remarks on Nominalization. In: R. Jacobs and P. Rosenbaum (eds.) ''Reading in English Transformational Grammar'', 184–221. Waltham: Ginn. and further developed by Ray Jackendoff (1974, 1977a, 1977bJackendoff, Ray (1977b) Constraints on Phrase Structure Rules, in P. W. Culicover, T. Wasow & A. Akmajian (eds.), ''Formal Syntax'', Academic Press, New York, pp. 249–83.), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
