Sub-ordinate clause begins with conjunctions like (who, which, that, when, how, where, while, if, whether, because, since, as, though, although, till, until, unless, before, after, so that, whenever, wherever, whoever, whatever etc.)
- I know where he lives.
- I do not know what his name is.
- While there is life there is hope.
- We eat so that we can survive.

Conjunctions are used in compound sentences are (and, but, or, for, nor, also, however, moreover, thus, so, therefore, else, still, as well as, accordingly, otherwise, yet, not yet, but also, either or, neither nor, on the contrary etc.)
