Notes

GENERAL INFO

Air is a masculine noun (m.) meaning "air" (the atmosphere, a tune/melody), or "look/appearance."

USAGE

It's used for the atmosphere (*l'air frais* - fresh air) and musical tunes (*un air de musique* - a tune). Crucially, "avoir l'air" means "to look/seem" (*Il a l'air triste* - He looks sad).

TRAPS

Do not confuse "air" with English "heir" (which is *héritier* in French) or "area" (*zone* or *superficie*). Remember to use *avoir* (to have) with "l'air" for "to seem/look," not *être* (to be).
