Learn Spanish (Latin America): Nosotros hablamos francés en casa.

To say "we do something" with regular -ar verbs, you drop the -ar ending and add -amos. So, hablar (to speak) becomes hablamos (we speak).

Can I leave out the word Nosotros and just say Hablamos francés en casa?

Yes! Because the ending -amos in hablamos only ever goes with "we", the word nosotros is optional. Spanish speakers often leave it out unless they want to add emphasis.

Why is francés written with a lowercase 'f'?

In Spanish, names of languages and nationalities (like francés, inglés, or español) are not capitalized unless they are the first word of a sentence.

Why do we use en casa here instead of en la casa?

En casa is a common set phrase that means "at home." If you say en la casa, it translates more literally to "in the house," referring to the physical building rather than the concept of being home.
