BUT HOW TO IDENTIFY WORDS WITH L' ARTICLE , example: l'animal (animal)  is masculine,  and l'armoire (wardrobe) is feminine,  and l'assiette (plate) is masculine ????

It says here that 'my nose is small but their noses are big' is translated to 'Mon nez est petit, mais leurs nez sont gros' . Is there a certain reason why it is "gros" isntead of "grand" ? Or is it just an optional thing?

Can anyone refer me to the lesson as to why "je me suis brossé les dents"   brossé has no extra e and the speaker is a woman. Has to do with "les dents" being the direct object, I think, but would love to read the lesson.

Is there any trick as such to consider them? I often find myself confused in the gender parts. Thanks
