- Many of these words involve making somebody believe something 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 somebody in authority who they trusted to look after their interests. If somebody takes you in, they may do it by acting a part and using words and charm effectively. If somebody cheats/fools/tricks/cons you, they may get something from you and make you feel stupid. However, somebody might fool you just as a joke; and to trick somebody is sometimes seen as a clever thing to do, if the person being tricked is seen as a bad person who deserves it.
