Verb

A verb, from the Latin verbum meaning word, is a word (part of speech) that in syntax 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. Verbs have tenses: present, to indicate that an action is being carried out; past, to indicate that an action has been done; future, to indicate that an action will be done. 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.). Latin and the Romance languages inflect verbs for tense–aspect–mood (abbreviated 'TAM'), and they agree in person and number (but not in gender, as for example in Polish) with the subject. Japanese, like many languages with SOV word order, inflects verbs for tense-aspect-mood, as well as other categories such as negation, but shows absolutely no agreement with the subject - it is a strictly dependent-marking language. On the other hand, Basque, Georgian, and some other languages, have polypersonal agreement: the verb agrees with the subject, the direct object, and even the secondary object if present, a greater degree of head-marking than is found in most European languages. 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 three 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 nonfinite, namely, not inflected for tense, and have various special forms such as infinitives, participles or gerunds. An intransitive verb is one that does not have a direct object. Intransitive verbs may be followed by an adverb (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.' A transitive verb is followed by a noun or noun phrase. 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 (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.'
