What does “au quotidien” mean in French?

Quotidien means “daily,” but it also works as a noun: le quotidien is your daily routine, the ordinary life you lead each day. Au quotidien means “day to day” or “in everyday life”: apprendre une langue au quotidien is learning a language as part of your normal days. It’s a little more natural than tous les jours when you mean ongoing habits.

The noun has a second job: un quotidien is a daily newspaper (Le Monde est un quotidien). The video’s advice uses it as routine: te servir de ton quotidien, “make use of your daily life,” with three moments to borrow: breakfast, your commute (tes trajets), and writing your to-do lists in the language you’re learning. Related: la vie quotidienne, “daily life.”
