Idioms are groups of words with a fixed order, and a particular meaning, different from the meanings of each of their words put together. (Phrasal verbs can also be idioms; they are said to be ‘idiomatic’ when their meaning is unpredictable.)
For example, do you know what it means to ‘meet one’s match’ in English? It means to meet someone who is as good as oneself, or even better, in some skill or quality.
Do you know what it means to ‘let the cat out of the bag’? Can you guess?
