Expression (linguistics)
In syntax and grammar, a phrase is a group of words or singular word acting as a grammatical unit. For instance, the English expression "the very happy squirrel" is a noun phrase which contains the adjective phrase "very happy". Phrases can consist of a single word or a complete sentence. In theoretical linguistics, phrases are often analyzed as units of syntactic structure such as a constituent. Common and technical use There is a difference between the common use of the term ''phrase'' and its technical use in linguistics. In common usage, a phrase is usually a group of words with some special idiomatic meaning or other significance, such as "all rights reserved", "economical with the truth", "kick the bucket", and the like. It may be a euphemism, a saying or proverb, a fixed expression, a figure of speech, etc.. In linguistics, these are known as phrasemes. In theories of syntax, a phrase is any group of words, or sometimes a single word, which plays a particular role w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syntax
In linguistics, syntax () is the study of how words and morphemes combine to form larger units such as phrases and sentences. Central concerns of syntax include word order, grammatical relations, hierarchical sentence structure ( constituency), agreement, the nature of crosslinguistic variation, and the relationship between form and meaning (semantics). There are numerous approaches to syntax that differ in their central assumptions and goals. Etymology The word ''syntax'' comes from Ancient Greek roots: "coordination", which consists of ''syn'', "together", and ''táxis'', "ordering". Topics The field of syntax contains a number of various topics that a syntactic theory is often designed to handle. The relation between the topics is treated differently in different theories, and some of them may not be considered to be distinct but instead to be derived from one another (i.e. word order can be seen as the result of movement rules derived from grammatical relations).

Phraseme
A phraseme, also called a set phrase, idiomatic phrase, multi-word expression (in computational linguistics), or idiom, is a multi-word or multi-morphemic utterance whose components include at least one that is selectionally constrained or restricted by linguistic convention such that it is not freely chosen. In the most extreme cases, there are expressions such as ''X kicks the bucket'' ≈ ‘person X dies of natural causes, the speaker being flippant about X’s demise’ where the unit is selected as a whole to express a meaning that bears little or no relation to the meanings of its parts. All of the words in this expression are chosen restrictedly, as part of a chunk. At the other extreme, there are collocations such as ''stark naked'', ''hearty laugh'', or ''infinite patience'' where one of the words is chosen freely (''naked'', ''laugh'', and ''patience'', respectively) based on the meaning the speaker wishes to express while the choice of the other (intensifying) word (''s ...

Adjective Phrase
An adjective phrase (or adjectival phrase) is a phrase whose head is an adjective. Almost any grammar or syntax textbook or dictionary of linguistics terminology defines the adjective phrase in a similar way, e.g. Kesner Bland (1996:499), Crystal (1996:9), Greenbaum (1996:288ff.), Haegeman and Guéron (1999:70f.), Brinton (2000:172f.), Jurafsky and Martin (2000:362). The adjective can initiate the phrase (e.g. ''fond of steak''), conclude the phrase (e.g. ''very happy''), or appear in a medial position (e.g. ''quite upset about it''). The dependents of the head adjective—i.e. the other words and phrases inside the adjective phrase—are typically adverb or prepositional phrases, but they can also be clauses (e.g. ''louder than you are''). Adjectives and adjective phrases function in two basic ways, attributively or predicatively. An attributive adjective (phrase) precedes the noun of a noun phrase (e.g. ''a very happy'' man). A predicative adjective (phrase) follows a linking verb a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adverb Phrase
In linguistics, an ''adverbial phrase'' ("AdvP") is a multi-word expression operating adverbially: its syntactic function is to modify other expressions, including verbs, adjectives, adverbs, adverbials, and sentences. Adverbial phrases can be divided into two types: complement adverbs and modifier adverbs. For example, in the sentence ''She sang very well'', the expression ''very well'' is an adverbial phrase, as it modifies the verb ''to sing''. More specifically, the adverbial phrase ''very well'' contains two adverbs, ''very'' and ''well'': while ''well'' modifies the verb to convey information about the manner of singing (for example, ''She sang well'' versus ''She sang badly''), ''very'' is a degree modifier that conveys information about the degree to which the action of singing well was accomplished (for example, ''Not only did she sing well, she sang very well''). Types The following examples illustrate some of the most common types of adverbial phrases. All adverbial phras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noun
A noun () is a word that generally functions as the name of a specific object or set of objects, such as living creatures, places, actions, qualities, states of existence, or ideas.Example nouns for: * Living creatures (including people, alive, dead or imaginary): ''mushrooms, dogs, Afro-Caribbeans, rosebushes, Nelson Mandela, bacteria, Klingons'', etc. * Physical objects: ''hammers, pencils, Earth, guitars, atoms, stones, boots, shadows'', etc. * Places: ''closets, temples, rivers, Antarctica, houses, Grand Canyon, utopia'', etc. * Actions: ''swimming, exercises, diffusions, explosions, flight, electrification, embezzlement'', etc. * Qualities: ''colors, lengths, deafness, weights, roundness, symmetry, warp speed,'' etc. * Mental or physical states of existence: ''jealousy, sleep, heat, joy, stomachache, confusion, mind meld,'' etc. Lexical categories (parts of speech) are defined in terms of the ways in which their members combine with other kinds of expressions.

Head (linguistics)
In linguistics, the head or nucleus of a phrase is the word that determines the syntactic category of that phrase. For example, the head of the noun phrase ''boiling hot water'' is the noun ''water''. Analogously, the head of a compound is the stem that determines the semantic category of that compound. For example, the head of the compound noun ''handbag'' is ''bag'', since a handbag is a bag, not a hand. The other elements of the phrase or compound modify the head, and are therefore the head's ''dependents''. Headed phrases and compounds are called ''endocentric'', whereas ''exocentric'' ("headless") phrases and compounds (if they exist) lack a clear head. Heads are crucial to establishing the direction of branching. Head-initial phrases are right-branching, head-final phrases are left-branching, and head-medial phrases combine left- and right-branching. Basic examples Examine the following expressions: :::big red dog :::birdsong The word ''dog'' is the head of ''big red dog' ...

Constituent (linguistics)
In syntactic analysis, a constituent is a word or a group of words that function as a single unit within a hierarchical structure. The constituent structure of sentences is identified using ''tests for constituents''. These tests apply to a portion of a sentence, and the results provide evidence about the constituent structure of the sentence. Many constituents are phrases. A phrase is a sequence of one or more words (in some theories two or more) built around a head lexical item and working as a unit within a sentence. A word sequence is shown to be a phrase/constituent if it exhibits one or more of the behaviors discussed below. The analysis of constituent structure is associated mainly with phrase structure grammars, although dependency grammars also allow sentence structure to be broken down into constituent parts. Tests for constituents in English Tests for constituents are diagnostics used to identify sentence structure. There are numerous tests for constituents that are co ...

Syntactic Category
A syntactic category is a syntactic unit that theories of syntax assume. Word classes, largely corresponding to traditional parts of speech (e.g. noun, verb, preposition, etc.), are syntactic categories. In phrase structure grammars, the ''phrasal categories'' (e.g. noun phrase, verb phrase, prepositional phrase, etc.) are also syntactic categories. Dependency grammars, however, do not acknowledge phrasal categories (at least not in the traditional sense). Word classes considered as syntactic categories may be called ''lexical categories'', as distinct from phrasal categories. The terminology is somewhat inconsistent between the theoretical models of different linguists. However, many grammars also draw a distinction between ''lexical categories'' (which tend to consist of content words, or phrases headed by them) and ''functional categories'' (which tend to consist of function words or abstract functional elements, or phrases headed by them). The term ''lexical category'' therefore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dependency Grammar
Dependency grammar (DG) is a class of modern grammatical theories that are all based on the dependency relation (as opposed to the ''constituency relation'' of phrase structure) and that can be traced back primarily to the work of Lucien Tesnière. Dependency is the notion that linguistic units, e.g. words, are connected to each other by directed links. The (finite) verb is taken to be the structural center of clause structure. All other syntactic units (words) are either directly or indirectly connected to the verb in terms of the directed links, which are called ''dependencies''. Dependency grammar differs from phrase structure grammar in that while it can identify phrases it tends to overlook phrasal nodes. A dependency structure is determined by the relation between a word (a head) and its dependents. Dependency structures are flatter than phrase structures in part because they lack a finite verb phrase constituent, and they are thus well suited for the analysis of languages ...

Phrase Structure Grammar
The term phrase structure grammar was originally introduced by Noam Chomsky as the term for grammar studied previously by Emil Post and Axel Thue (Post canonical systems). Some authors, however, reserve the term for more restricted grammars in the Chomsky hierarchy: context-sensitive grammars or context-free grammars. In a broader sense, phrase structure grammars are also known as ''constituency grammars''. The defining trait of phrase structure grammars is thus their adherence to the constituency relation, as opposed to the dependency relation of dependency grammars. Constituency relation In linguistics, phrase structure grammars are all those grammars that are based on the constituency relation, as opposed to the dependency relation associated with dependency grammars; hence, phrase structure grammars are also known as constituency grammars. Any of several related theories for the parsing of natural language qualify as constituency grammars, and most of them have been develope ...

The House At The End Of The Street
''House at the End of the Street'' is a 2012 American psychological thriller film directed by Mark Tonderai that stars Jennifer Lawrence. The film's plot revolves around a teenage girl, Elissa, who along with her newly divorced mother Sarah, moves to a new neighborhood only to discover that the house at the end of the street was the site of a gruesome double homicide committed by a thirteen-year-old girl named Carrie Anne who had disappeared without a trace four years prior. Elissa then starts a relationship with Carrie Anne's older brother Ryan, who lives in the same house, but nothing is as it appears to be. Although filming had been completed in 2010, the film was not released until 2012 by Relativity Media. Despite a negative response from critics, the film was a moderate commercial success. Plot Newly divorced medical doctor Sarah Cassidy (Elisabeth Shue) and her 17-year-old daughter Elissa ( Jennifer Lawrence) move to a small, upscale suburb. They are disturbed to discover ...

Parse Tree
A parse tree or parsing tree or derivation tree or concrete syntax tree is an ordered, rooted tree that represents the syntactic structure of a string according to some context-free grammar. The term ''parse tree'' itself is used primarily in computational linguistics; in theoretical syntax, the term ''syntax tree'' is more common. Concrete syntax trees reflect the syntax of the input language, making them distinct from the abstract syntax trees used in computer programming. Unlike Reed-Kellogg sentence diagrams used for teaching grammar, parse trees do not use distinct symbol shapes for different types of constituents. Parse trees are usually constructed based on either the constituency relation of constituency grammars (phrase structure grammars) or the dependency relation of dependency grammars. Parse trees may be generated for sentences in natural languages (see natural language processing), as well as during processing of computer languages, such as programming languages. ...
