(Compound Sentence)
In a Simple Sentence, we have one finite verb and it is the main clause of the sentence.
In a Complex Sentence, we have two clauses, one main clause and one subordinate clause.
In a Compound Sentence, we have two main clauses connected by a coordinating conjunction “and”, “so”, “but”, etc.
The subordinate clauses in complex sentences are caused by the following conjunctions:
- For time concept: When, While, As, After, Before
- For cause concept: Because, Since, As
- For concession concept: Though, Although, Even though
- For condition concept: If, Even if, As if, Unless
- For inherent concept: So that
