Être une vraie girouette
Idioms are a vital part of every language for they add colour and imagery to your speech, therefore making it more expressive. Learning idioms in a foreign language will allow you to communicate in a much more natural and authentic way. While grammar and vocabulary are the building blocks of a language, these expressions will make you sound like a native speaker!
