Some compound words (like bus rapid transit, dog whistle, or identity theft) don’t appear on the drop-down list when you enter them into the search window. If a compound term doesn’t appear in the drop-down list, try entering the term into the search window and then hit the search button (instead of the “enter” key). Alternatively, begin searches for compound terms with a quotation mark.

al·terna·tive·ly adv.

Usage Note: A traditional view holds that alternative should be used only when the number of choices involved is exactly two. This reasoning is based on the word's historical relation to Latin alter, "the other of two." Even in the 1960s, some 58 percent of the Usage Panel did not favor this edict, and now that majority is overwhelming. In 2009, fully 87 percent of the Panel accepted the sentence There are plenty of alternatives to straightforward advertising, and 85 percent accepted There are many new antibiotic alternatives to penicillin. Constructions like a number of alternatives must now be considered standard. · As an adjective, alternative can mean "allowing or requiring a choice between two or more things," as in We wrote an alternative statement in case the first was rejected by the board. It may also refer to a variant or substitute in cases where no choice is involved, as in We will do our best to secure alternative employment for employees displaced by the closing of the factory. In our 2009 survey, 87 percent of the Usage Panel accepted this sentence. Interestingly, only 52 percent accepted alternate when used in the same sentence.
