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.
Lexical semantics, as a subfield of linguistic semantics, is the study of word meanings. It includes the study of how words structure their meaning, how they act in grammar and compositionality, and the relationships between the distinct senses and uses of a word.
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 reformulating the ideas of Zellig Harris (1951), and further developed by Ray Jackendoff, 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 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.
In linguistics, the minimalist program is a major line of inquiry that has been developing inside generative grammar since the early 1990s, starting with a 1993 paper by Noam Chomsky.
Theta roles are the names of the participant roles associated with a predicate: the predicate may be a verb, an adjective, a preposition, or a noun. If an object is in motion or in a steady state as the speakers perceives the state, or it is the topic of discussion, it is called a theme. The participant is usually said to be an argument of the predicate. In generative grammar, a theta role or θ-role is the formal device for representing syntactic argument structure—the number and type of noun phrases—required syntactically by a particular verb. For example, the verb put requires three arguments.
A dummy pronoun, also known as an expletive pronoun, is a deictic pronoun that fulfills a syntactical requirement without providing a contextually explicit meaning of its referent. As such, it is an example of exophora.
Principles and parameters is a framework within generative linguistics in which the syntax of a natural language is described in accordance with general principles and specific parameters that for particular languages are either turned on or off. For example, the position of heads in phrases is determined by a parameter. Whether a language is head-initial or head-final is regarded as a parameter which is either on or off for particular languages. Principles and parameters was largely formulated by the linguists Noam Chomsky and Howard Lasnik. Many linguists have worked within this framework, and for a period of time it was considered the dominant form of mainstream generative linguistics.
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, nominalization or nominalisation is the use of a word that is not a noun as a noun, or as the head of a noun phrase. This change in functional category can occur through morphological transformation, but it does not always. Nominalization can refer, for instance, to the process of producing a noun from another part of speech by adding a derivational affix, but it can also refer to the complex noun that is formed as a result.
In linguistics, the projection principle is a stipulation proposed by Noam Chomsky as part of the phrase structure component of generative-transformational grammar. The projection principle is used in the derivation of phrases under the auspices of the principles and parameters theory.
The theta-criterion is a constraint on x-bar theory that was first proposed by Noam Chomsky as a rule within the system of principles of the government and binding theory, called theta-theory (θ-theory). As theta-theory is concerned with the distribution and assignment of theta-roles, the theta-criterion describes the specific match between arguments and theta-roles (θ-roles) in logical form (LF):
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, the empty category principle (ECP) was proposed in Noam Chomsky's syntactic framework of government and binding theory. The ECP is supposed to be a universal syntactic constraint that requires certain types of empty categories, namely traces, to be properly governed.
In linguistics, an empty category, which may also be referred to as a covert category, is an element in the study of syntax that does not have any phonological content and is therefore unpronounced. Empty categories exist in contrast to overt categories which are pronounced. When representing empty categories in tree structures, linguists use a null symbol (∅) to depict the idea that there is a mental category at the level being represented, even if the word(s) are being left out of overt speech. The phenomenon was named and outlined by Noam Chomsky in his 1981 LGB framework, and serves to address apparent violations of locality of selection — there are different types of empty categories that each appear to account for locality violations in different environments. Empty categories are present in most of the world's languages, although different languages allow for different categories to be empty.
In generative linguistics, PRO is a pronominal determiner phrase (DP) without phonological content. As such, it is part of the set of empty categories. The null pronoun PRO is postulated in the subject position of non-finite clauses. One property of PRO is that, when it occurs in a non-finite complement clause, it can be bound by the main clause subject or the main clause object. The presence of PRO in non-finite clauses lacking overt subjects allows a principled solution for problems relating to binding theory.
The Specified Subject Condition (SSC) is a condition proposed in Chomsky (1973) which restricts the application of certain syntactic transformational grammar rules. In many ways it is a counterpart to the Tensed-S Condition (TSC), applying to non-finite clauses and complex determiner phrases (DPs) which are not covered by the TSC. The rule was formalized as follows, where a "specified subject" is a lexical subject i.e. a subject with semantic content, like a proper noun, a complex DP, or a pronominal:
Merge is one of the basic operations in the Minimalist Program, a leading approach to generative syntax, when two syntactic objects are combined to form a new syntactic unit. Merge also has the property of recursion in that it may be applied to its own output: the objects combined by Merge are either lexical items or sets that were themselves formed by Merge. This recursive property of Merge has been claimed to be a fundamental characteristic that distinguishes language from other cognitive faculties. As Noam Chomsky (1999) puts it, Merge is "an indispensable operation of a recursive system ... which takes two syntactic objects A and B and forms the new object G={A,B}" (p. 2).
In linguistics, locality refers to the proximity of elements in a linguistic structure. Constraints on locality limit the span over which rules can apply to a particular structure. Theories of transformational grammar use syntactic locality constraints to explain restrictions on argument selection, syntactic binding, and syntactic movement.
In linguistics and grammar, Avalency refers to the property of a predicate, often a verb, taking no arguments. Valency refers to how many and what kinds of arguments a predicate licenses—i.e. what arguments the predicate selects grammatically. Avalent verbs are verbs which have no valency, meaning that they have no logical arguments, such as subject or object. Languages known as pro-drop or null-subject languages do not require clauses to have an overt subject when the subject is easily inferred, meaning that a verb can appear alone. However, non-null-subject languages such as English require a pronounced subject in order for a sentence to be grammatical. This means that the avalency of a verb is not readily apparent, because, despite the fact that avalent verbs lack arguments, the verb nevertheless has a subject. According to some, avalent verbs may have an inserted subject, which is syntactically required, yet semantically meaningless, making no reference to anything that exists in the real world. An inserted subject is referred to as a pleonastic, or expletive it. Because it is semantically meaningless, pleonastic it is not considered a true argument, meaning that a verb with this it as the subject is truly avalent. However, others believe that it represents a quasi-argument, having no real-world referent, but retaining certain syntactic abilities. Still others consider it to be a true argument, meaning that it is referential, and not merely a syntactic placeholder. There is no general consensus on how it should be analyzed under such circumstances, but determining the status of it as a non-argument, a quasi-argument, or a true argument, will help linguists to understand what verbs, if any, are truly avalent. A common example of such verbs in many languages is the set of verbs describing weather. In providing examples for the avalent verbs below, this article must assume the analysis of pleonastic it, but will delve into the other two analyses following the examples.
In syntax, verb-initial (V1) word order is a word order in which the verb appears before the subject and the object. In the more narrow sense, this term is used specifically to describe the word order of V1 languages. V1 clauses only occur in V1 languages and other languages with a dominant V1 order displaying other properties that correlate with verb-initiality and that are crucial to many analyses of V1. V1 languages are estimated to make up 12–19% of the world’s languages.
