Grade 7 Grammar Lesson 12 Sentences: simple, compound and complex

A clause that doesn’t give a complete meaning by itself, and is a part of a longer sentence is called a sub- ordinate clause.

A subordinate clause is usually a noun clause, an adjective clause or an adverb clause, which forms part of a main clause to give completeness to a sentence.

We may join a sub-ordinate clause to a main or independent clause using sub-ordinate conjunctions such as the following.

  • if/ whether/ that and wh- words (to form noun clause)

  • who, whose, which and that (to form adjective clause)

  • when, whenever, before, after, till, since, while

    and as (for adverb clause of time)

  • because, since, as and for (adverb clause of reason)

  • that and so that (adverb clause of purpose)

  • if and unless (adverb clause of condition)

  • though, although, even though and even if

(adverb clause of contrast and concession)

A sentence having one or more sub-ordinate clauses is called a complex sentence.

If the sub-ordinate adverb clause comes first, we use a comma.
