The distinction between coordinate and subordinate clauses

الملخص EN

The present study deals with important terms in grammar; namely coordination and subordination in order to shed the light on the differences between them.

The study has come out with certain points that coordination is a process used to form two or more categories by the same types by using and, or, but etc.

Subordination that forms subordinate clause which is also called independent clause that contains a string of words by using subordinators as since, because, although …etc.

Such a clause cannot stand alone but usually forms a major part of a sentence.

Both coordination and subordination used for linking units, but for subordination the unit is subordinated to the other.

In addition clauses begin with coordinator normally cannot be moved in front of the preceding clause without changing the relationship of clauses, on the other hand, Subordinate clause has a flexible position in a sentence.

Finally, the study has concluded that the coordinators allow ellipsis of the subject of the clause they introduce if the subject has a reference with the preceding clause .subordination generally, does not allow ellipsis.
