Many of these words involve making sb believe sth that is not true, but some of them are more disapproving than others. Deceive is probably the worst because people typically deceive friends, relations and others who know and trust them. People may feel cheated/betrayed by sb in authority who they trusted to look after their interests. If sb takes you in they may do it by acting a part and using words and charm effectively. If sb cheats/fools/tricks/cons you, they may get sth from you and make you feel stupid. However, sb might fool you just as a joke; and to trick sb is sometimes seen as a clever thing to do, if the person being tricked is seen as a bad person who deserves it. |
