1055. Simple sentences may be combined in two different ways. The added
sentence may be I. Coordinate; or II. Subordinate.
Thus, in _he died and we lived_, the two sentences are coordinate, that
is, of equal rank. But in _he died that we might live_, the sentence
beginning with _that_ is subordinate. In either combination the separate
sentences are often called _Clauses_ or _Members_, in contradistinction
to the more comprehensive sentence of which they are parts.
