Конструктивный синтаксис (структурный)

The verb

1. 
   The general characteristics of English verbs.
   
2. 
   Grammatically relevant semantic subclasses of English verbs.
   

The verb as a notional (знаменательная) of speech has the categorial meaning of dynamic process which includes not only actions as such (to build), but also states (to become), different types of attitude or feelings (to like) etc. Another words the verb denotes dynamic properties (динамические характеристики признаки) of substance. Formally or morphologically the verb is characterized by a specific set of word – building affixes (to reread, to widen (расширять), to activate). The verb is usually treated as the most complex part of speech because it has more word - changing categories than any other notional part speech. It is changed according to the categories of tense, aspect (категория вида), voice (залог), mood (наклонение), person (лицо) and number.
Such a wide range of forms is mainly due to the importance of the function that the verb performs in the sentence: its primary (основная) function is that of a predicate. This syntactic function is the central organizing member of the sentence because it is characterized by the greatest syntactic valency (валентность) among all other syntactic function. The complexity of the verb (сложность глагола) is always manifested (проявляется) in the system of its grammatically relevant subclasses.
On the upper level all the verbs according to semantic value fall into two subclasses:

1. 
   Notional verbs (смысловые глаголы) and functional (служебные) (semi functional - полуслужебные) verbs. Notional verbs have full nominative value: they are independent in the expression of the process (to read, to work etc). Functional and semi functional verbs have partial (частичные) nominative value: they are depended on other words in the denotation of the process (must).

      Functional and semi functional verbs are further subdivided into a number of groups:
