Idioms are the 'flavor' of a language and are often the hardest part for learners to master because they aren't logical.

When not to use

Don't confuse with 'proverb' (which gives advice) or 'slang' (which is just informal vocabulary).

Fun facts

  • The idiom 'break a leg' actually comes from the theater, where it was considered bad luck to wish someone 'good luck'.
