The verb is called the significant part of speech, which denotes any action or condition. The verb in Russian answers the questions “what to do?”, “What does?” and "what to do?" Note that the concept of a state or action is relative: it can be both physical actions or movements in space, and the activity of the senses or mental state. In addition, this part of speech expresses thought processes, becoming signs, designating speech, and so on. Despite the difference in lexical meanings, all these words have a categorical meaning of processuality.
The verb as part of speech is rich in various grammatical categories and their inherent forms. In addition to categories that are common to other parts of speech (category of person, number and gender), the verb has categories inherent only to it (type, mood, voice, voice).
The morphological categories of this part of speech are different in composition. Thus, the categories of pledge and type are inherent in all verb forms, and the remaining morphological categories deal only with certain forms. The mood category is inherent in all conjugated verbs, however, it is not peculiar to the infinitive, gerupunion and participle. The category of time is inherent in forms of exclusively indicative mood, while the category of face is also characteristic of forms of imperative mood. The number is characteristic of all forms, except for the infinitive initial form and adverbial participle, and the gender in the singular is only to the subjunctive forms and past tense, as well as participles.
The verb as part of speech divides all its forms into two groups: conjugated and non-conjugated. Three classes of forms are distinguished in academic grammar: conjugated forms, infinitive, participle, and participle. In this case, conjugated forms are contrasted by grammatical values of time, number, mood, person, gender.
The change of verbs by moods, as well as tenses (the indicative mood of the verb), persons (the indicative and imperative moods), numbers and gender are called conjugation, and the forms that are formed are called conjugated forms.
Non-conjugated forms of verbs include infinitive, participles and participles, which differ from conjugated verbs in that they have no inflectional grammatical meanings. However, while the participles and the infinitive are represented in only one form, the participles can be contrasted in terms of pledges and tenses and can be changed in numbers and births.
At the same time, both conjugated and non-conjugated verb forms are combined into one system of forms, since they have common features, among which are the commonality of lexical collaterals, collateral and species formations and controls, as well as a common opportunity to be explained with an adverb.
The verb as part of the speech in the sentence often expresses the predicate, however, the syntactic function that it expresses depends on its form. Conjugate forms of the verb are also called predicative, since they are used as a simple or compound verb predicate. The participles appear in the sentence as an agreed definition, as well as the nominal part of the compound nominal predicate. The participles express circumstances or a secondary predicate. The participles and participles, being secondary members of a sentence, are called attributive.
The infinitive - the initial form of the verb - can be any member of the sentence: subject, predicate, and main member of an impersonal sentence, and definition, and addition, and circumstance. Infinitive - a form from the base of which almost all verb forms are formed. So, for example, the past tense of the indicative mood, the subjunctive verbs, the participle in the past tense, the participle of the passive voice and the participle are formed from the basis of the infinitive.
The verb as part of speech is very important in the language, since it is he who forms the basis of any sentence and makes our speech coherent and full of meaning.
