The verb has finite and non-finite forms, the latter being also called verbals. The verbals, unlike the finite forms of the verb, don't express person, number or mood. Therefore they cannot be used as the predicate of a sentence.
Like the finite forms of the verb verbals have tense and voice distinctions, but their tense distinctions differ greatly from those of the finite verb. There are 3 verbals in English: the participle, the gerund and the infinitive.
Coordination (SR1) – syntagmatic relations of independence. SR1 can be observed on the phrase, sentence and text levels. Coordination may be symmetric and asymmetric. Symmetric coordination is characterized by complete interchangeability of its elements – pens and pencils. Asymmetric coordination occurs when the position of elements is fixed: ladies and gentlemen. Forms of connection within SR1 may be copulative (you and me), disjunctive (you or me), adversative (strict but just) and causative-consecutive (sentence and text level only).
Syntactic form may be described as the distributional formula of the unit (pattern). John hits the ball – N1 + V + N2.
