Agreement

In languages where the verb is inflected, it often agrees with its primary argument (the subject) in person, number or gender. With the exception of the verb ''to be'', English shows distinctive agreements only in the third person singular, present tense form of verbs, which are marked by adding "-s" ( ''walks'') or "-es" (''fishes''). The rest of the persons are not distinguished in the verb (''I walk'', ''you walk'', ''they walk'', etc.).

Types

Verbs vary by type, and each type is determined by the kinds of words that accompany it and the relationship those words have with the verb itself. Classified by the number of their valency arguments, usually four basic types are distinguished: intransitives, transitives, ditransitives and double transitive verbs. Some verbs have special grammatical uses and hence complements, such as copular verbs (i.e., ''be''); the verb ''do'' used for ''do''-support in questioning and negation; and tense or aspect auxiliaries, e.g., ''be'', ''have'' or ''can''. In addition, verbs can be non-finite (not inflected for person, number, tense, etc.), such special forms as infinitives, participles or gerunds.

Intransitive verbs

An intransitive verb is one that does not have a direct object. Intransitive verbs may be followed by an

adverb An adverb is a word or an expression that generally modifies a verb, an adjective, another adverb, a determiner, a clause, a preposition, or a sentence. Adverbs typically express manner, place, time, frequency, degree, or level of certainty by ...

(a word that addresses how, where, when, and how often) or end a sentence. For example: "The woman ''spoke'' softly." "The athlete ''ran'' faster than the official." "The boy ''wept''."

Transitive verbs

A transitive verb is followed by a noun or

noun phrase 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 ...

. These noun phrases are not called predicate nouns, but are instead called direct objects because they refer to the object that is being acted upon. For example: "My friend ''read'' the newspaper." "The teenager ''earned'' a speeding ticket." A way to identify a transitive verb is to invert the sentence, making it passive. For example: "The newspaper ''was read'' by my friend." "A speeding ticket ''was earned'' by the teenager."

Ditransitive verbs

Ditransitive verbs (sometimes called Vg verbs after the verb ''give'') precede either two noun phrases or a noun phrase and then a prepositional phrase often led by ''to'' or ''for''. For example: "The players ''gave'' their teammates high fives." "The players ''gave'' high fives to their teammates." When two noun phrases follow a transitive verb, the first is an indirect object, that which is receiving something, and the second is a direct object, that being acted upon. Indirect objects can be noun phrases or prepositional phrases.

Double transitive verbs

Double transitive verbs (sometimes called Vc verbs after the verb ''consider'') are followed by a noun phrase that serves as a direct object and then a second noun phrase, adjective, or

phrase. The second element (noun phrase, adjective, or infinitive) is called a complement, which completes a

clause In language, a clause is a Constituent (linguistics), constituent or Phrase (grammar), phrase that comprises a semantic predicand (expressed or not) and a semantic Predicate (grammar), predicate. A typical clause consists of a subject (grammar), ...

that would not otherwise have the same meaning. For example: "The young couple ''considers'' the neighbors wealthy people." "Some students ''perceive'' adults quite inaccurately." "Sarah ''deemed'' her project to be the hardest she has ever completed."

Copular verbs

Copular verbs ( linking verbs) include ''be'', ''seem'', ''become'', ''appear'', ''look'', and ''remain''. For example: "Her daughter ''was'' a writing tutor." "The singers ''were'' very nervous." "His mother ''looked'' worried." "Josh ''remained'' a reliable friend." These verbs precede nouns or adjectives in a sentence, which become predicate nouns and predicate adjectives. Copulae are thought to 'link' the predicate adjective or noun to the subject. They can also be followed by an adverb of place, which is sometimes referred to as a predicate adverb. For example: "My house ''is'' down the street." The main copular verb ''be'' is manifested in eight forms ''be'', ''is'', ''am'', ''are'', ''was'', ''were'', ''been'', and ''being'' in English.

Valency

The number of arguments that a verb takes is called its ''valency'' or ''valence''. Verbs can be classified according to their valency: * Avalent (valency = 0): the verb has neither a subject nor an object. Zero valency does not occur in English; in some languages such as

Mandarin Chinese Mandarin ( ; zh, s=, t=, p=Guānhuà, l=Mandarin (bureaucrat), officials' speech) is the largest branch of the Sinitic languages. Mandarin varieties are spoken by 70 percent of all Chinese speakers over a large geographical area that stretch ...

, weather verbs like ''snow(s)'' take no subject or object. * Intransitive (valency = 1, monovalent): the verb only has a subject. For example: "he runs", "it falls". * Transitive (valency = 2, divalent): the verb has a subject and a direct object. For example: "she eats fish", "we hunt nothing". * Ditransitive (valency = 3, trivalent): the verb has a subject, a direct object, and an indirect object. For example: "He gives her a flower" or "She gave John the watch." *A few English verbs, particularly those concerned with financial transactions, take four arguments, as in "Pat₁ sold Chris₂ a lawnmower₃ for $20₄" or "Chris₁ paid Pat₂ $20₃ for a lawnmower₄".

Impersonal and objective verbs

Weather verbs often appear to be impersonal (subjectless, or avalent) in null-subject languages like Spanish, where the verb ''llueve'' means "It rains". In English, French and German, they require a dummy pronoun and therefore formally have a valency of 1. As verbs in Spanish incorporate the subject as a TAM suffix, Spanish is not actually a null-subject language, unlike Mandarin (see above). Such verbs in Spanish also have a valency of 1. Intransitive and transitive verbs are the most common, but the impersonal and objective verbs are somewhat different from the norm. In the objective, the verb takes an object but no subject; the nonreferent subject in some uses may be marked in the verb by an incorporated dummy pronoun similar to that used with the English weather verbs. Impersonal verbs in null subject languages take neither subject nor object, as is true of other verbs, but again the verb may show incorporated dummy pronouns despite the lack of subject and object phrases.

Valency marking

Verbs are often flexible with regard to valency. In non-valency marking languages such as English, a transitive verb can often drop its object and become intransitive; or an intransitive verb can take an object and become transitive. For example, in English the verb ''move'' has no grammatical object in ''he moves'' (though in this case, the subject itself may be an implied object, also expressible explicitly as in ''he moves himself''); but in ''he moves the car'', the subject and object are distinct and the verb has a different valency. Some verbs in English have historically derived forms that show change of valency in some causative verbs, such as ''fall-fell-fallen'':''fell-felled-felled''; ''rise-rose-risen'':''raise-raised-raised''; ''cost-cost-cost'':''cost-costed-costed''. In valency marking languages, valency change is shown by inflecting the verb in order to change the valency. In Kalaw Lagaw Ya of Australia, for example, verbs distinguish valency by argument agreement suffixes and TAM endings: * Nui mangema "He arrived earlier today" (mangema today past singular subject active intransitive perfective) * Palai mangemanu "They ualarrived earlier today" * Thana mangemainu "They luralarrived earlier today" ''Verb structure:'' manga-i- umberTAM "arrive+active+singular/dual/plural+TAM" * Nuidh wapi manganu "He took the fish o that placeearlier today" (manganu today past singular object attainative transitive perfective) * Nuidh wapi mangamanu "He took the two fish o that placeearlier today" * Nuidh wapi mangamainu "He took the hree or morefish o that placeearlier today" ''Verb structure:'' manga-Ø- umberTAM "arrive+attainative+singular/dual/plural+TAM" The verb stem manga- 'to take/come/arrive' at the destination takes the active suffix -i (> mangai-) in the intransitive form, and as a transitive verb the stem is not suffixed. The TAM ending -nu is the general today past attainative perfective, found with all numbers in the perfective except the singular active, where -ma is found.

Tense, aspect, and modality

Depending on the language, verbs may express ''grammatical tense'', ''aspect'', or ''modality''.

Tense

Grammatical tense Östen Dahl, ''Tense and Aspect Systems'', Blackwell, 1985. is the use of auxiliary verbs or

inflection In linguistic Morphology (linguistics), morphology, inflection (less commonly, inflexion) is a process of word formation in which a word is modified to express different grammatical category, grammatical categories such as grammatical tense, ...

s to convey whether the action or state is before, simultaneous with, or after some reference point. The reference point could be the time of utterance, in which case the verb expresses absolute tense, or it could be a past, present, or future time of reference previously established in the sentence, in which case the verb expresses relative tense.

Aspect

Aspect expresses how the action or state occurs through time. Important examples include: *

perfective aspect The perfective aspect ( abbreviated ), sometimes called the aoristic aspect, is a grammatical aspect that describes an action viewed as a simple whole, i.e., a unit without interior composition. The perfective aspect is distinguished from the ...

, in which the action is viewed in its entirety through completion (as in "I saw the car") * imperfective aspect, in which the action is viewed as ongoing; in some languages a verb could express imperfective aspect more narrowly as: **habitual aspect, in which the action occurs repeatedly (as in "I used to go there every day"), or ** continuous aspect, in which the action occurs without pause; continuous aspect can be further subdivided into *** stative aspect, in which the situation is a fixed, unevolving state (as in "I know French"), and *** progressive aspect, in which the situation continuously evolves (as in "I am running") * perfect, which combines elements of both aspect and tense and in which both a prior event and the state resulting from it are expressed (as in "he has gone there", i.e. "he went there and he is still there") * discontinuous past, which combines elements of a past event and the implication that the state resulting from it was later reversed (as in "he did go there" or "he has been there", i.e. "he went there but has now come back") Aspect can either be lexical, in which case the aspect is embedded in the verb's meaning (as in "the sun shines", where "shines" is lexically stative), or it can be grammatically expressed, as in "I am running."

Mood and modality

Modality expresses the speaker's attitude toward the action or state given by the verb, especially with regard to degree of necessity, obligation, or permission ("You must go", "You should go", "You may go"), determination or willingness ("I will do this no matter what"), degree of probability ("It must be raining by now", "It may be raining", "It might be raining"), or ability ("I can speak French"). All languages can express modality with

s, but some also use verbal forms as in the given examples. If the verbal expression of modality involves the use of an auxiliary verb, that auxiliary is called a modal verb. If the verbal expression of modality involves inflection, we have the special case of mood; moods include the

indicative A realis mood ( abbreviated ) is a grammatical mood which is used principally to indicate that something is a statement of fact; in other words, to express what the speaker considers to be a known state of affairs, as in declarative sentence Dec ...

(as in "I am there"), the subjunctive (as in "I wish I ''were'' there"), and the imperative ("Be there!").

Voice

The

Klaiman, M. H., ''Grammatical Voice (Cambridge Studies in Linguistics)'', Cambridge Univ. Press, 1991. of a verb expresses whether the subject of the verb is performing the action of the verb or whether the action is being performed on the subject. The two most common voices are the active voice (as in "I saw the car") and the

passive voice A passive voice construction is a grammatical voice construction that is found in many languages. In a clause with passive voice, the grammatical subject expresses the ''theme'' or ''patient'' of the main verb – that is, the person or thing ...

(as in "The car was seen by me" or simply "The car was seen").

Non-finite forms

Most languages have a number of

verbal noun Historically, grammarians have described a verbal noun or gerundial noun as a verb form that functions as a noun. An example of a verbal noun in English is 'sacking' as in the sentence "The ''sacking'' of the city was an epochal event" (wherein ...

s that describe the action of the verb. In the Indo-European languages, verbal adjectives are generally called

participle In linguistics, a participle (; abbr. ) is a nonfinite verb form that has some of the characteristics and functions of both verbs and adjectives. More narrowly, ''participle'' has been defined as "a word derived from a verb and used as an adject ...

s. English has an active participle, also called a present participle; and a passive participle, also called a past participle. The active participle of ''break'' is ''breaking'', and the passive participle is ''broken''. Other languages have attributive verb forms with tense and aspect. This is especially common among verb-final languages, where attributive verb phrases act as

relative clause A relative clause is a clause that modifies a noun or noun phrase and uses some grammatical device to indicate that one of the arguments in the relative clause refers to the noun or noun phrase. For example, in the sentence ''I met a man who wasn ...
