There are several types of wordplay used in cryptics. One is straightforward definition substitution using parts of a word. For example, in one puzzle by Mel Taub, the answer "IMPORTANT" is given the clue "To bring worker into the country may prove significant". The explanation is that to "import" means "to bring into the country", the "worker" is a worker "ant", and "significant" means "important". Here, "significant" is the straight definition (appearing here at the end of the clue), "to bring worker into the country" is the wordplay definition, and "may prove" serves to link the two. Note that in a cryptic clue, there is almost always only one answer that fits both the definition and the wordplay, so that when one sees the answer, one knows that it is the right answer—although it can sometimes be a challenge to figure out "why" it is the right answer. A good cryptic clue should provide a fair and exact definition of the answer, while at the same time being deliberately misleading.
