Are there any other 'CONJUNCTIONS' too?
Broadly, conjunctions are classified into two types- co-ordinating conjunctions and subordinating conjunctions.
Co-ordinating conjunctions join two sentences of equal ranks. They are: for,and, but, also, or etc. There are some conjunctions that are used in pairs, for example: either-or, neither-nor, not only-but also etc.
Subordinating conjunctions are used to join two clauses one of which is dependent upon the other. For example, after, before, although, till, unless, while, that, if, since, than etc.
