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: In standard usage, good is an adjective, and the only verbs it should be used with are linking verbs such as be, seem, or appear: The future looks good. The soup tastes good. It should not be used as an adverb with other verbs: The car runs well (not good). Thus, The dress fits well and looks good. See Usage Note at well2.
