Clause = Subject + Verb
Clause is a combination of words which contains subject and a verb. It may be a complete sentence or part of a sentence that conveys proper meaning. It is quite different from a phrase where the subject-verb combination is not necessary.
Types of clauses
1. Independent clause
2. Dependent clause
1. Independent clause: (also known as main clause, conjoining clause, principal clause, and co-ordinate clause) it can stand independently
E.g. I went to the library
Two independent clauses can be joined together with the help of these independent conjunctions
And, yet, but, or, so.
2. Dependent clause: (also known as auxiliary clause, embedding clause, reason clause, and sub-ordinate clause). It is dependent on the main (independent) clause.
E.g., he says that he was coming.
A dependent clause can be joined together with a main clause and other independent clauses through these Dependent (subordinate) conjunctions.
