Alternative \Al*ter"na*tive\, n. [Cf. F. alternative, LL.
1. An offer of two things, one of which may be chosen, but
not both; a choice between two things, so that if one is
taken, the other must be left.
...so, as you can see, you may use either word interchangeably or
confine yourself to, "alternate,' since we needn't leave the one
<thing> when choosing the other.
