This word should only be used when a choice may be made. It has recently been driving out other more suitable words, and constantly appears where there is no choice, and the proper word is some such adjective as other, fresh, different, revised, substitute. Possibly this strange popularity comes from the attractive Jingle " alternative accommodation ", sanctioned by the legislature, in the sense of accommodation other than that already occupied. Mistrust alternative deeply: always ask yourself whether there is in fact a choice, and if there is not, select some other word.

It is pedantry to say that, because of its derivation, alternative must not be used where the choices are more than two. See Changes In The Meaning Of Words.
