Infinitive in the context of "Verb"

Bulgarian is an Eastern South Slavic language spoken in Southeast Europe, primarily in Bulgaria. It is the language of the Bulgarians.

Along with the closely related Macedonian language (collectively forming the East South Slavic languages), it is a member of the Balkan sprachbund and South Slavic dialect continuum of the Indo-European language family. The two languages have several characteristics that set them apart from all other Slavic languages, including the elimination of case declension, the development of a suffixed definite article, and the lack of a verb infinitive. They retain and have further developed the Proto-Slavic verb system (albeit analytically). One such major development is the innovation of evidential verb forms to encode for the source of information: witnessed, inferred, or reported.

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.

Verb phrases generally are divided among two types: finite, of which the head of the phrase is a finite verb; and nonfinite, where the head is a nonfinite verb, such as an infinitive, participle or gerund. Phrase structure grammars acknowledge both types, but dependency grammars treat the subject as just another verbal dependent, and they do not recognize the finite verbal phrase constituent. Understanding verb phrase analysis depends on knowing which theory applies in context.

A finite verb is a verb that contextually complements a subject, which can be either explicit (like in the English indicative) or implicit (like in null subject languages or the English imperative). A finite transitive verb or a finite intransitive verb can function as the root of an independent clause. Finite verbs are distinguished from non-finite verbs such as infinitives, participles, gerunds etc.

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 sacking is a gerund form of the verb sack).

A verbal noun, as a type of nonfinite verb form, is a term that some grammarians still use when referring to gerunds, gerundives, supines, and nominal forms of infinitives. In English however, verbal noun has most frequently been treated as a synonym for gerund.

An auxiliary verb (abbreviated aux) 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 learning, the principal parts of a verb are the most fundamental forms of a verb that can be conjugated into any form of the verb. The concept originates in the humanist Latin schools, where students learned verbs by chanting them in the four key forms from which all other forms can be deduced, for example:

Not all languages have to be taught in this way. In French, for example, regular verbs can be deduced from a single form, the infinitive, and irregular verbs are too random to be systematized under fixed parts. But the concept can be carried over to many languages in which the verbs have some kind of "regular irregularity", i.e. irregularity always occurs at the same place in an otherwise regular system.
