In French, 'la maison' can also refer to a company or business in some contexts, but this is less common.
Remember that 'maison' is feminine, so adjectives must agree in gender and number (e.g., 'une petite maison').
The plural of 'maison' is 'maisons', pronounced /me.zɔ̃/.
From Old French 'maisun', derived from Latin 'mansio' meaning 'dwelling' or 'stay'.
In formal contexts, 'la maison' can sometimes refer to a company or institution, but this is less common in everyday speech.
