What does “registre élevé”, “registre courant” and “registre familier” mean? This is because from the book I am studying, the structure of the question changes — Avez-vous des timbres ?, Est-ce que vous avez des timbres ? and Vous avez des timbres ?, respectively.
There are three "registres" which are level languages. These levels depends of your public. "registre élevé/soutenu", "registre courant/normal" and "registre familier".
Registre Elevé / Soutenu

Registre courant/ Normal
