==Content clause==
{{Main article|Content clause}}
A content clause, also known as a "noun clause", provides content implied or commented upon by its main clause. It can be a [[Subject (grammar)|subject]], [[predicate nominative]], [[direct object]], [[appositive]], [[indirect object]], or object of the [[preposition]]. Some of the English words that introduce content clauses are ''that, who'' (and formal ''whom''), ''whoever'' (and formal ''whomever''), ''whether, why, what, how, when'', and ''where''. Notice that some of these words also introduce relative and adverbial clauses. A clause is a content clause if a pronoun (''he, she, it,'' or ''they'') could be substituted for it.

Examples: 
*I know ''who said that''. (I know them. The dependent clause serves as the object of the main-clause verb "know".)
*''Whoever made that assertion'' is wrong. (They are wrong. The dependent clause serves as the subject of the main clause.)

In English, in some instances the [[English relative clauses#That as relativizer instead of relative pronoun|subordinator ''that'' can be omitted]].

Example 1:
*I know ''that he is here.''
*I know ''he is here''.

Example 2:
*I think ''that it is pretty''. (less common)
*I think ''it is pretty''. (more common)
