Circumstances, as well as a person, may have this effect (their work experience has discouraged them from a career in engineering ), and the object of the verb can be an action rather than a person (inflation discourages investment ). Discourage can also be used to express official disapproval that stops short of an actual order (the Hospital discourages smoking ). ■ To deter someone from doing something involves creating, constituting, or pointing out a serious obstacle that will confront them if they go ahead with their plans (high fees deter some patients from visiting a consultant ). The object of deter can also be an action (the main aim of cruise missiles is to deter an attack ). The word is often associated with preventing crime and military aggression (even an unwired alarm box is often sufficient to deter a burglar ), and this sense is continued in the noun deterrent (NATO's nuclear deterrent ). ■ To dissuade someone is to use rational arguments that make them see the difficulty or undesirable nature of their proposed course of action (we tried to dissuade Steven from marrying ). The object of dissuade is always a person (or body of people ), not an action or event. These notes show fine distinctions in meaning between closely related synonyms to help you find the best word.
