Celia - if you are still reading,don't take any of this guff to heart.
i found this,might help,
"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." Note that in a cryptic clue, there is almost always only one answer that fits both the definition and the wordplay, so that when you see the answer, you know 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 exactly explain the answer, while at the same time giving a meaningful surface reading. In our sample clue, a more exact wordplay phrasing would be "To bring into the country a worker may prove significant", since "ant" follows "import:" IMPORT + ANT. Note however, that the surface reading is then not as smooth as the original."
