The most common dependent clause forms include subordinate clauses, relative clauses, interrogative clauses, and that-clauses. This means that the subject of a dependent clause will be preceded by a subordinator or an interrogative or a nominal-that. In most cases the subject will be replaced by a relative. Moreover, as we will discuss shortly, each of these dependent clauses function in a very specific and prescribed way.
Remember, the dependent marker will either precede the subject or replace the subject. On some occasions, a THAT dependent marker will be deleted. In most cases, those are nominal clauses serving as the direct object of another clause.
