Clause:is a group of words containing a subject and predicate and forming part of a sentence.The 2 kinds of clauses are the independent clause(also called the main clause)and the dependent clause(subordinate clause)
eg:I saw him when I came in
here the main clause or the independent clause is I saw him
what you have to bear in mind that the independent clause expresses a complete idea and it can stand alone as a sentence
Types of sentences:
the simple sentences:contain one idea
eg:Ice melts
the compound sentence:contains 2 independent clauses joined by coordinating conjuctions:and,but,or,either....or,neither......n or etc
eg:she did not attend her lessons ,but copied all of them
the complex sentence:includes 1 independent clasue and 1 subordinate clause
eg:he repeated his behavior although I warmed him
the complex compound sentence:is a combination of a compound sentence and a complex one
eg:while I go to the party,Jack refuses,but Sam hesitated.
