This Walking Classroom podcast focuses on idioms. Idioms are groups of words that, when said together, have an understood meaning that is different from what the words actually mean. For example, “to be on the moon” doesn’t actually mean that a person is on the moon, it is an idiom that people say when someone is very distracted or really excited about something. All languages have idioms, and sometimes it can be difficult for people who are learning a new language to understand the meanings behind them.
