Formal:
* Nous (pronounced "noo") - This is the most common and formal way to say "we." It's used in writing and when addressing someone you don't know well, such as a teacher or someone in a position of authority.
Informal:
* On (pronounced "ohn") - This is a less formal way to say "we," often used in everyday conversation. It's more similar to the English "one" in phrases like "one should always be polite."
* On est (pronounced "ohn eh") - This is a shortened form of "on est," meaning "we are." It's used in everyday conversation and is more informal than "nous."
* On a (pronounced "ohn ah") - This is a shortened form of "on a," meaning "we have." It's used in everyday conversation and is more informal than "nous."
Other considerations:
* Gender: In some cases, the French word for "we" will change depending on the gender of the people in the group. For example, if you're talking about a group of women, you would use "nous," but if you're talking about a group of men, you would use "nous."
Here are some examples:
* Formal: Nous allons au cinéma. (We are going to the cinema.)
* Informal: On va au cinéma. (We are going to the cinema.)
* Informal: On est prêts. (We are ready.)
Ultimately, the best way to choose the right word for "we" in French is to consider the context and the level of formality.
