Answer:
True
Explanation:
A clause is a part of the sentence that contains a verb. A typical clause consists of subject + predicate, the latter typically a verb phrase, a verb with any objects and other modifiers. However, the subject is sometimes not said or explicit, often the case in null-subject languages if the subject is retrievable from context, but it sometimes also occurs in other languages such as English (as in imperative sentences and non-finite clauses).
We have some kind of clauses:
SV clauses
Subject+verb. They are usually declarative.
Verb first clauses They can express a yes/no question via subject–auxiliary inversion, they express a condition as an embedded clause or they express a command via imperative mood.
Wh clauses
They always contain a wh-word. Wh-words often serve to help express a constituent question.
Relative clauses
They can be standard SV-clauses if they are introduced by that or lack a relative pronoun entirely, or they can be wh-clauses if they are introduced by a wh-word that serves as a relative pronoun.
Argument clauses
Argument clauses can appear as subjects, as objects, and as obliques.
Adjunct clauses
Adjunct clauses are embedded clauses that modify an entire predicate-argument structure.
Predicative clauses
An embedded clause can also function as a predicative expression.
