Proverbs and set expressions

Ce n'est pas la mer à boire…

Native speakers use set expressions and proverbs constantly. At C2 you should understand them in context and use the common ones naturally.

Everyday idioms

  • Ce n'est pas la mer à boire.It's not that hard.
  • Il m'a posé un lapin.He stood me up.
  • J'ai d'autres chats à fouetter.I've got bigger fish to fry.
  • Elle est tombée dans les pommes.She fainted.
  • Il met toujours son grain de sel.He always sticks his oar in.
  • Ça coûte les yeux de la tête.It costs an arm and a leg.

Proverbs

  • Petit à petit, l'oiseau fait son nid.Little by little, the bird builds its nest.
  • L'habit ne fait pas le moine.Don't judge a book by its cover.

Playing with them

French speakers often twist proverbs for humour, and journalists use them in headlines. Knowing the original lets you catch the joke.

  • Qui va à la chasse perd sa place.Leave your seat and you lose it.

Use idioms where they fit: one well-chosen expression sounds natural; five in a row sounds like a textbook.
