Nous in French primarily means “we” — the subject pronoun for the first-person plural.

Quick points and examples:

• Subject (we):
  Nous allons au cinéma. — We are going to the cinema.
• Object (us): nous is also used as the direct/indirect object pronoun.
  Il nous voit. — He sees us.
  Donne-nous le livre. — Give us the book.
• Reflexive (ourselves): used in reflexive verbs:
  Nous nous lavons. — We wash ourselves.
• Prepositions: avec nous = with us, chez nous = at our place / at home.
• Pronunciation: [nu] (like “noo”).

Grammar tip: in spoken French, people often use on (literally “one”) to mean “we” informally: On y va ≈ Nous y allons.
