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: "Some contemporaries believed that capitalism and the rise of an international economy would prevent war among 'civilized' states" (John Howard Morrow).
To preclude is to exclude the possibility of an event or action: "a tranquillity which ... his wife's presence would have precluded" (John Henry Newman).
Avert and obviate imply that something, such as a difficulty or necessity, has been removed or avoided: The pilot's quick thinking averted an accident. The short duration of the journey obviated the need for large food supplies. Forestall usually suggests anticipatory measures taken to counteract, neutralize, or nullify the effects of something: We installed an alarm system to forestall break-ins.
