Synonyms: prevent, preclude, avert, obviate, forestall. These verbs mean to stop or hinder something from happening, especially by advance planning or action. Prevent implies anticipatory counteraction: "The surest way to prevent war is not to fear it" (John Randolph). To preclude is to exclude the possibility of the occurrence of an event or action: "a tranquillity which . . . his wife's presence would have precluded" (John Henry Newman). To avert is to ward off something about to happen: Only quick thinking on the pilot's part averted a disastrous accident. Obviate implies that something, such as a difficulty, has been anticipated and disposed of effectively: "the objections . . . having . . . been obviated in the preceding chapter" (Joseph Butler). Forestall usually suggests anticipatory measures taken to counteract, neutralize, or nullify the effects of something: We installed an alarm system to forestall break-ins.
