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.

Usage Note: Infer is sometimes confused with imply, but the distinction careful writers make between these words is a useful one. When we say that a speaker or sentence implies something, we mean that it is conveyed or suggested without being stated outright: When the mayor said that she would not rule out a business tax increase, she implied (not inferred) that some taxes might be raised. Inference, on the other hand, is the activity performed by a reader or interpreter in drawing conclusions that are not explicit in what is said: When the mayor said that she would not rule out a tax increase, we inferred that she had consulted with new financial advisers, since her old advisers favored tax reductions.
