Recognize common idioms and explain their non-literal meanings.
An idiom is a phrase whose real meaning is different from what the individual words literally say -- you have to already know the phrase to understand it. If someone says "it is raining cats and dogs," they do not mean animals are falling from the sky; they mean it is raining very hard.
English is full of idioms: "break a leg" means good luck, especially before a performance. "Piece of cake" means something is easy. "Hit the books" means study hard. "Under the weather" means feeling a little sick. Picturing the silly literal meaning is a fun way to notice that idioms are never meant word for word.
Mastery looks like: They can explain the non-literal meaning of common idioms and recognize that idioms are not meant to be taken word for word.
Common stumbles: Taking an idiom literally and getting confused instead of recognizing it as a set phrase with its own meaning.
