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). Diverse approaches, such as generative grammar and functional grammar, offer unique perspectives on syntax, reflecting its complexity and centrality to understanding human language.
In grammar, a phrase—called expression in some contexts—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. 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.
English grammar is the set of structural rules of the English language. This includes the structure of words, phrases, clauses, sentences, and whole texts.
An auxiliary verb is a verb that adds functional or grammatical meaning to the clause in which it occurs, so as to express tense, aspect, modality, voice, emphasis, etc. Auxiliary verbs usually accompany an infinitive verb or a participle, which respectively provide the main semantic content of the clause. An example is the verb have in the sentence I have finished my lunch. Here, the auxiliary have helps to express the perfect aspect along with the participle, finished. Some sentences contain a chain of two or more auxiliary verbs. Auxiliary verbs are also called helping verbs, helper verbs, or (verbal) auxiliaries. Research has been conducted into split inflection in auxiliary verbs.
In language, a clause is a constituent or phrase that comprises a semantic predicand and a semantic predicate. A typical clause consists of a subject and a syntactic predicate, the latter typically a verb phrase composed of a verb with or without any objects and other modifiers. However, the subject is sometimes unexpressed if it is easily deducible from the context, especially in null-subject language but also in other languages, including instances of the imperative mood in English.
In linguistics, a verb phrase (VP) is a syntactic unit composed of a verb and its arguments except the subject of an independent clause or coordinate clause. Thus, in the sentence A fat man quickly put the money into the box, the words quickly put the money into the box constitute a verb phrase; it consists of the verb put and its arguments, but not the subject a fat man. A verb phrase is similar to what is considered a predicate in traditional grammars.
A subject is one of the two main parts of a sentence.
In linguistics, word order is the order of the syntactic constituents of a language. Word order typology studies it from a cross-linguistic perspective, and examines how languages employ different orders. Correlations between orders found in different syntactic sub-domains are also of interest. The primary word orders that are of interest are
In syntax, verb-second (V2) word order is a sentence structure in which the finite verb of a sentence or a clause is placed in the clause's second position, so that the verb is preceded by a single word or group of words.
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.
In linguistics, a small clause consists of a subject and its predicate, but lacks an overt expression of tense. Small clauses have the semantic subject-predicate characteristics of a clause, and have some, but not all, properties of a constituent. Structural analyses of small clauses vary according to whether a flat or layered analysis is pursued. The small clause is related to the phenomena of raising-to-object, exceptional case-marking, accusativus cum infinitivo, and object control.
In linguistics, volition is a concept that distinguishes whether the subject, or agent of a particular sentence intended an action or not. Simply, it is the intentional or unintentional nature of an action. Volition concerns the idea of control and for the purposes outside of psychology and cognitive science, is considered the same as intention in linguistics. Volition can then be expressed in a given language using a variety of possible methods. These sentence forms usually indicate that a given action has been done intentionally, or willingly. There are various ways of marking volition cross-linguistically. When using verbs of volition in English, like "want" or "prefer", these verbs are not expressly marked. Other languages handle this with affixes, while others have complex structural consequences of volitional or non-volitional encoding.
In linguistics, inverse copular constructions, named after Moro (1997), are a type of inversion in English where canonical SCP word order is reversed in a sense, so that one appears to have the order PCS instead. The verb in these constructions is always the copula be. Inverse copular constructions are intriguing because they render the distinction between subject and predicative expression difficult to maintain. The confusion has led to focused study of these constructions, and their impact on the theory of grammar may be great since they appear to challenge the initial binary division of the sentence (S) into a subject noun phrase (NP) and a predicate verb phrase (VP), this division being at the core of all phrase structure grammars.
Subject–auxiliary inversion is a frequently occurring type of inversion in the English language whereby a finite auxiliary verb – taken here to include finite forms of the copula be – appears to "invert" with the subject. The word order is therefore Aux-S (auxiliary–subject), which is the opposite of the canonical SV (subject–verb) order of declarative clauses in English. The most frequent use of subject–auxiliary inversion in English is in the formation of questions, although it also has other uses, including the formation of condition clauses, and in the syntax of sentences beginning with negative expressions.
Syntactic movement is the means by which some theories of syntax address discontinuities. Movement was first postulated by structuralist linguists who expressed it in terms of discontinuous constituents or displacement. Some constituents appear to have been displaced from the position in which they receive important features of interpretation. The concept of movement is controversial and is associated with so-called transformational or derivational theories of syntax. Representational theories, in contrast, reject the notion of movement and often instead address discontinuities with other mechanisms including graph reentrancies, feature passing, and type shifters.
Do-support, in English grammar, is the use of the auxiliary verb do, to form negated clauses and constructions which require subject–auxiliary inversion, such as questions.
This article describes the syntax of clauses in the English language, chiefly in Modern English. A clause is often said to be the smallest grammatical unit that can express a complete proposition. But this semantic idea of a clause leaves out much of English clause syntax. For example, clauses can be questions, but questions are not propositions. A syntactic description of an English clause is that it is a subject and a verb. But this too fails, as a clause need not have a subject, as with the imperative, and, in many theories, an English clause may be verbless. The idea of what qualifies varies between theories and has changed over time.
Subject–verb inversion in English is a type of inversion marked by a predicate verb that precedes a corresponding subject, e.g., "Beside the bed stood a lamp". Subject–verb inversion is distinct from subject–auxiliary inversion because the verb involved is not an auxiliary verb.
Betty J. Birner is an American linguist. Her research focuses on pragmatics and discourse analysis, particularly the identification of the types of contexts appropriate for sentences with marked word order.
An echo question is a question that seeks to confirm or clarify another speaker's utterance, by repeating it back in some form. For example:
A: I'm moving to Greenland. B: You're moving where?
