Preventing_or_letting

A Potential_hindrance or an Agent (via their actions) keeps an Event from taking place, or despite the possibility of prevent the Event, do not do so. Lexical units which indicate that the event is not prevented, e.g. allow.v, are marked with the semantic type "Negative". Some lexical units, like avert and avoid indicate that the Potential_hindrance or Agent would have been affected if the Event occurred. Rain prevented the ball game from taking place. He could have stopped the riot . The government narrowly averted a coup . She allowed more than a few mistakes to happen . Technology has permitted firms to link together more closely. Unlike DOS , Windows lets you get on with something else when sending a fax. Liberalization allows easier entry into particular markets . Mesh allows the water to circulate normally through the aquarium. Unlike in the Thwarting frame, the Potential_hindrance or Agent does not directly prevent the actions of an individual, but rather affects the world in such a way that an Event cannot occur.
