why "les" it's just one corn, isn't?
I'm pretty sure 'corn' is a mass noun, so you can't have 'a corn' just like you can't have 'a water' or 'a sand'. But correct me if I'm wrong.
I don't understand the plural of this word. I thought you can't count 'corn'. Are they counting the cobs?
"le mais" ok, but "les mais" a tittle weird!! isn't?
How can you tell if a word is feminine or masculine?
