Answer:
Definition of preclude: to make impossible by necessary consequence : rule out in advance.
Step-by-step explanation:
Preclude is often used in legal writing, where it usually refers to making something legally impossible. A new law may be passed by Congress to preclude any suits of a certain kind against a federal agency, for example. Some judges have found that the warnings on cigarette packs preclude any suits against the tobacco companies by lung-cancer sufferers. But there are plenty of nonlegal uses as well. Bad weather often precludes trips to the beach, and a lack of cash might preclude any beach vacation at all.
