After the previous I serve you the classification of noun, now i'll talk about verb. here is the complete classification of verb which will make you easier to understand. verb divided as several kinds, Verb is the most complex part of speech. Its varying arrangements with nouns determine the different kinds of sentences: sentences, questions, commands, exclamation. Frank (1990:47) divides verbs into the following types:
a. Classified by complement of verb.
- Predicating / linking verbs. A predicating verb is the chief word in the predicate that says something about the subject. The predicating word (or predicator) has traditionally been called a verb of action (e.g. babies cry), but has actually been interpreted to include most non-action verbs that are not linking verbs (e.g. I remember him).
- Transitive / intransitive verbs. A transitive verb takes a direct object (e.g. He is reading a book); an intransitive verb does not require an object (e.g. He is walking in the park). Only transitive verbs may be used in the passive voice (e.g. The book was returned by him quickly). All linking verbs are intransitive.
- Reflexive verbs. They require one of the compounds with –self (reflexive pronoun) as its object (e.g. express oneself, wash oneself, and pride oneself). Some verbs may be used with or without the reflexive pronoun object (e.g. He washed (himself) and dressed (himself) quickly).
b. Classified by form of verb.
- Auxiliary / lexical verbs. Two or more words may be joined together into a single verb phrase that functions as the full verb of the predicate. The first part of the phrase is the auxiliary and the second part is the lexical verb (will be, arriving). The lexical verb carries the chief burden of semantic content. The auxiliary verb acts as a helping verb to the lexical verb by adding either a structural element that marks differences in tense, voice, mood and aspect, or that signal questions and negatives; or a semantic colouring such as ability, possibility or necessity (modal auxiliary).
- Finite / non-finite verbs. The form for these verbs is determined by the function which the verb has in a sentence. A finite verb is a lexical verb with or without auxiliaries that acts as the full verb in the predicate. It is limited by all the grammatical properties a verb may have –person, number, tense, voice, etc.
c. Two words joined into one.
- Adjective + verb (e.g. ill-treat, dry-clean). Many of these verbs are hyphenated, whereas their noun equivalents are written as two separate words (e.g. ill treatment, dry cleaning).
- Noun + verb (e.g. hamstring, waterproof). Some of these compounds may represent back formations which have been coined by dropping an –er agent-denoting suffix – e.g. sleepwalk (from the original sleep-walker)
d. Two separate words functioning as one vocabulary unit.
Such a verb is composed of a verb plus a prepositional form –give-up, over look, find out. English makes great use of such two-part verbs for expanding the vocabulary.
