Theoretical Grammar

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.


2. Classifications of English verbs
According to different principles of classification, classifications can be morphological, lexical-morphological, syntactical and functional.
A. 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 im port, transport - to transport, expanded (with the help of suffixes and prefixes): cultivate, justify, overcome, composite (correspond to composite nouns): to blackmail), 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 past tenses and Participle II verbs can be regular and irregular.
B. 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.
C. Syntactic classifications. According to the nature 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.):
