An idiom is a group of words that has a meaning that is different from the usual meanings of the individual words in it. An idiom has a figurative meaning instead of a literal meaning.
A literal meaning is the most basic sense of a word or phrase. A figurative meaning expresses an idea that is different or interesting in order to create a mental picture.
Some examples of idioms include 'cost an arm and a leg', which does not mean you literally have to pay for something with an arm and a leg. But figuratively it means that something is very expensive and costs a lot of money.
Let's take another example. 'One's cup of tea', which means something one likes or prefers. The idiom is often used in the negative form to describe something someone doesn't like.
