Object (grammar) in the context of Clauses

In grammar, a noun is a word that represents a concrete or abstract thing, like living creatures, places, actions, qualities, states of existence, and ideas. A noun may serve as an object or subject within a phrase, clause, or sentence.

In linguistics, nouns constitute a lexical category (part of speech) defined according to how its members combine with members of other lexical categories. The syntactic occurrence of nouns differs among languages.

A noun phrase – or NP or nominal (phrase) – is a phrase that usually has a noun or pronoun as its head, and has the same grammatical functions as a noun. Noun phrases are very common cross-linguistically, and they may be the most frequently occurring phrase type.

Noun phrases often function as verb subjects and objects, as predicative expressions, and as complements of prepositions. One NP can be embedded inside another NP; for instance, some of his constituents has as a constituent the shorter NP his constituents.

In grammar, the nominative case (abbreviated NOM), subjective case, straight case, or upright case is one of the grammatical cases of a noun or other part of speech, which generally marks the subject of a verb, or (in Latin and formal variants of English) a predicative nominal or adjective, as opposed to its object, or other verb arguments. Generally, the noun "that is doing something" is in the nominative, and the nominative is often the form listed in dictionaries.

In grammar, a phrase—called an expression in some contexts—is a group of one or more words 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", or "kick the bucket". 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 within the syntactic structure of a sentence. It does not have to have any special meaning or significance, or even exist anywhere outside of the sentence being analyzed, but it must function there as a complete grammatical unit. For example, in the sentence Yesterday I saw an orange bird with a white neck, the words an orange bird with a white neck form a noun phrase, or a determiner phrase in some theories, which functions as the object of the sentence.

In linguistics, grammatical relations (also called grammatical functions, grammatical roles, or syntactic functions) are functional relationships between constituents in a clause. The standard examples of grammatical functions from traditional grammar are subject, direct object, and indirect object. In recent times, the syntactic functions (more generally referred to as grammatical relations), typified by the traditional categories of subject and object, have assumed an important role in linguistic theorizing, within a variety of approaches ranging from generative grammar to functional and cognitive theories. Many modern theories of grammar are likely to acknowledge numerous further types of grammatical relations (e.g. complement, specifier, predicative, etc.).

The role of grammatical relations in theories of grammar is greatest in dependency grammars, which tend to posit dozens of distinct grammatical relations. Every head-dependent dependency bears a grammatical function.

In language, a clause is a constituent or phrase that comprises a semantic predicand (expressed or not) 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 languages but also in other languages, including instances of the imperative mood in English.

A complete simple sentence contains a single clause with a finite verb. Complex sentences contain at least one clause subordinated to (dependent on) an independent clause (one that could stand alone as a simple sentence), which may be co-ordinated with other independents with or without dependents. Some dependent clauses are non-finite, i.e. they do not contain any element/verb marking a specific tense.

A verb is a word that generally conveys an action (bring, read, walk, run, learn), an occurrence (happen, become), or a state of being (be, exist, stand). In the usual description of English, the basic form, with or without the particle to, is the infinitive. In many languages, verbs are inflected (modified in form) to encode tense, aspect, mood, and voice. A verb may also agree with the person, gender or number of some of its arguments, such as its subject, or object. In English, three tenses exist: present, to indicate that an action is being carried out; past, to indicate that an action has been done; and future, to indicate that an action will be done, expressed with the auxiliary verb will or shall.

A grammatical case is a category of nouns and noun modifiers (determiners, adjectives, participles, and numerals) that corresponds to one or more potential grammatical functions for a nominal group in a wording. In various languages, nominal groups consisting of a noun and its modifiers belong to one of a few such categories. For instance, in English, one says I see them and they see me: the nominative pronouns I / they represent the perceiver, and the accusative pronouns me/them represent the phenomenon perceived. Here, nominative and accusative are cases, that is, categories of pronouns corresponding to the functions they have in representation.

English has largely lost its inflected case system but personal pronouns still have three cases, which are simplified forms of the nominative, accusative (including functions formerly handled by the dative), and genitive cases. They are used with personal pronouns: subjective case (I, you, he, she, it, we, they, who, whoever), objective case (me, you, him, her, it, us, them, whom, whomever), and possessive case (my, mine; your, yours; his; her, hers; its; our, ours; their, theirs; whose; whosever). Forms such as I, he, and we are used for the subject ("I kicked John"), and forms such as me, him, and us are used for the object ("John kicked me").

In linguistic typology, ergative–absolutive alignment is a type of morphosyntactic alignment in which the subject of an intransitive verb behaves like the object of a transitive verb, and differently from the subject of a transitive verb. Examples include Basque, Georgian, Mayan, Tibetan, Sumerian, and certain Indo-European languages (such as Pashto and the Kurdish languages and many Indo-Aryan languages like Hindustani). It has also been attributed to the Semitic modern Aramaic (also called Neo-Aramaic) languages. Ergative languages are classified into two groups: those that are morphologically ergative but syntactically behave as accusative (for instance, Basque, Pashto and Urdu) and those that, on top of being ergative morphologically, also show ergativity in syntax. Languages that belong to the former group are more numerous than those to the latter.

The ergative-absolutive alignment is in contrast to nominative–accusative alignment, which is observed in English and most other Indo-European languages, where the single argument of an intransitive verb ("She" in the sentence "She walks") behaves grammatically like the agent (subject) of a transitive verb ("She" in the sentence "She finds it") but different from the object of a transitive verb ("her" in the sentence "He likes her"). When ergative–absolutive alignment is coded by grammatical case, the case used for the single argument of an intransitive verb and the object of a transitive verb is the absolutive, and the case used for the agent of a transitive verb is the ergative. In nominative-accusative languages, the case for the single argument of an intransitive verb and the agent of a transitive verb is the nominative, while the case for the direct object of a transitive verb is the accusative.

A predicative expression (or just predicative) is part of a clause predicate, and is an expression that typically follows a copula or linking verb, e.g. be, seem, appear, or that appears as a second complement (object complement) of a certain type of verb, e.g. call, make, name, etc. The most frequently acknowledged types of predicative expressions are predicative adjectives (also predicate adjectives) and predicative nominals (also predicate nominals). The main trait of all predicative expressions is that they serve to express a property that is assigned to a "subject", whereby this subject is usually the clause subject, but at times it can be the clause object. A primary distinction is drawn between predicative (also predicate) and attributive expressions. Further, predicative expressions are typically not clause arguments, and they are also typically not clause adjuncts. There is hence a three-way distinction between predicative expressions, arguments, and adjuncts.

The terms predicative expression on the one hand, and subject complement and object complement on the other hand overlap in meaning to a large extent.

Adpositions are a class of words used to express spatial or temporal relations (in, under, towards, behind, ago, etc.) or mark various semantic roles (of, for). The most common adpositions are prepositions (which precede their complement) and postpositions (which follow their complement).

An adposition typically combines with a noun phrase, this being called its complement, or sometimes object. English generally has prepositions rather than postpositions – words such as in, under and of precede their objects, such as "in England", "under the table", "of Jane" – although there are a few exceptions including ago and notwithstanding, as in "three days ago" and "financial limitations notwithstanding". Some languages that use a different word order have postpositions instead (like Turkic languages) or have both types (like Finnish). The phrase formed by an adposition together with its complement is called an adpositional phrase (or prepositional phrase, postpositional phrase, etc.). Such a phrase can function as a grammatical modifier or complement in a wide range of types of phrases.

A topic-prominent language is a language that organizes its syntax to emphasize the topic–comment structure of the sentence. The term is best known in American linguistics from Charles N. Li and Sandra Thompson, who distinguished topic-prominent languages, such as Korean and Japanese, from subject-prominent languages, such as English.

In Li and Thompson's (1976) view, topic-prominent languages have morphology or syntax that highlights the distinction between the topic and the comment (what is said about the topic). Topic–comment structure may be independent of the syntactic ordering of subject, verb and object.

In linguistic typology, subject–verb–object (SVO) is a sentence structure where the subject comes first, the verb second, and the object third. Languages may be classified according to the dominant sequence of these elements in unmarked sentences (i.e., sentences in which an unusual word order is not used for emphasis). English is included in this group. An example is "Sam ate apples."

SVO is the second-most common order by number of known languages, after SOV. Together, SVO and SOV account for more than 87% of the world's languages. The label SVO often includes ergative languages although they do not have nominative subjects.

In linguistic typology, a subject–object–verb (SOV) language is one in which the subject, object, and verb of a sentence always or usually appear in that order. If English were SOV, "Sam apples ate" would be an ordinary sentence, as opposed to the actual Standard English "Sam ate apples" which is subject–verb–object (SVO).

The term is often loosely used for ergative languages like Adyghe and Basque that in fact have agents instead of subjects.

In linguistics, valency or valence is the number and type of arguments and complements controlled by a predicate, content verbs being typical predicates. Valency is related, though not identical, to subcategorization and transitivity, which count only object arguments – valency counts all arguments, including the subject. The linguistic meaning of valency derives from the definition of valency in chemistry. Like valency found in chemistry, there is the binding of specific elements. In the grammatical theory of valency, the verbs organize sentences by binding the specific elements. Examples of elements that would be bound would be the complement and the actant. Although the term originates from valence in chemistry, linguistic valency has a close analogy in mathematics under the term arity.

The valency metaphor appeared first in linguistics in Charles Sanders Peirce's essay "The Logic of Relatives" in 1897, and it then surfaced in the works of a number of linguists decades later in the late 1940s and 1950s. Lucien Tesnière is credited most with having established the valency concept in linguistics. A major authority on the valency of the English verbs is Allerton (1982), who made the important distinction between semantic and syntactic valency.
