faire la vaisselle is 'to do the dishes' in French. The first 'a' stands for 'avoir' indicating that it is used in a past time.
Il = Ill Fait = Fay Mauvais = Mow-vay
il fait bon = the temperature is fine (not necessarily outside) il fait beau = the weather is fine
the weather is fine, the temperature is agreeable
It means "the weather is cold" Hope this helps! :3
