General characteristics of the verb

Grammatically the verb is the most complex part of speech, which denoting an action or a process. First of all it performs the central role in realizing predication - connection between situation in the utterance and reality. That is why the verb is of primary informative significance in an utterance. Besides, the verb possesses quite a lot of grammatical categories. Furthermore, within the class of verb various subclass divisions based on different principles of classification can be found.

Semantic features of the verb. The verb possesses the grammatical meaning of verbiality - the ability to denote a process developing in time. This meaning is inherent not only in the verbs denoting processes, but also in those denoting states, forms of existence, evaluations, etc.

Morphological features of the verb. The verb possesses the following grammatical categories: tense, aspect, voice, mood, person, number, finitude and phase. The common categories for finite and non-finite forms are voice, aspect, phase and finitude. The grammatical categories of the therb find their expression in synthetical and analytical forms. The formative elements expressing these categories are grammatical affixes, inner inflexion and function words. Some categories have only synthetical forms (person, number), others - only analytical (voice). There are also categories expressed by both synthetical and analytical forms (mood, tense, aspect).

Syntactic features. The most universal syntactic feature of verbs is their ability to be modified by adverbs. The second important syntactic criterion is the ability of the verb to perform the syntactic function of the predicate. However, this criterion is not absolute because only finite forms can perform this function while non-finite forms can be used in any function but predicate. And finally, any verb in the form of the infinitive can be combined with a modal verb.

Classifications of English verbs.

Classifications can be morphological, lexical-morphological, syntactical and functional.

Morphological classifications:

I. According to their stem-types all verbs fall into: simple (to go),sound-replacive (food - to feed, blood - to bleed), stress-replacive (import - to import, transport - to transport, expanded (with the help of suffixes and prefixes): cultivate, justify, overcome, composite (correspond to composite nouns): to mail), phrasal: to have a smoke, to give a smile (they always have an ordinary verb as an equivalent). 2. According to the way of forming the tenses and Participle II verbs can be regular and irregular.

Lexical-morphological classification is based on the implicit grammatical meanings of the verb. According to the implicit grammatical meaning of transitivity/intransitivity verbs fall into transitive and intransitive. According to the implicit grammatical meaning of stativeness/non-stativeness verbs fall into stative and dynamic. According to the implicit grammatical meaning of terminativeness/non-terminativeness verbs fall into terminative and durative. This classification is closely connected with the categories of Aspect and Phase.

Syntactic classification. thenature of predication (primary and secondary) all verbs fall into finite and non-finite. According to syntagmatic properties (valency) verbs can be of obligatory and optional valency, and thus they may have some directionality or be devoid of any directionality. In this way, verbs fall into the verbs of directed (to see, to take, etc.) and non-directed action (to arrive, to drizzle, etc.):

Functional classification. According to their functional significance verbs can be notional (with the full lexical meaning), semi-notional (modal verbs, link-verbs), auxiliaries.
