Bonjour
La famille Dupont est une grande famille.
the adjective grand (e) (s) (es) ...............
grand = masc. singulier ===> un grand + masc. noun <em>(un grand arbre)</em>
grande = fem. singulier ===> une grande + fem. noun <em>(une grande </em><u><em>famille)</em></u>
grands = masc. pluriel ====> des grands + masc. pluriel <em>(des grands arbres</em>)
grandes = fem. pluriel =====> des grandes + fem. plur. <em>(des grandes familles)</em>
Hi
A quelle heure partez-vous Mme et Mr Martin ? (I guess that was the question you got translated -badly- by Google)
what time are you leaving Mme and Mr Martin ?
Nous partons à sept heures.
(the answer is more "adequate with this question)
anyway the answer is correct ...!!!
Partir (= to leave)
je pars
tu pars
il/elle/on part
nous partons
vous partez
ils/elles partent
hope I helped !
