No confusion possible since you should hear "est" in the middle.
By the way, it is NOIRE (vache is feminine)
After learning "le chien" and "la chienne". I want to know how to distinguish a male cow and a female cow.
a male cow is a bull.
une vache -> un taureau
la vache qui rit
Nope, la vache qui rit est rouge !
Haha, d'accord! ;)
What is the difference between "noir" and "noire"?
un chien noir (masculine singular) - des chiens noirs (masculine plural)
une vache noire (feminine singular) - des vaches noires (feminine plural)
Can i write "The black cow" instead of "The cow is black"?
You can write it but it is wrong, since you dropped the verb.
Ok I get it, Learning french is more and more interesting!
Pronunciation wise can I tell the difference between "noir" and "noire"?
No, but since you know that "la vache" is feminine, "noire" must be in feminine as well.
Gosh, so do all color spellings change now with feminine Nouns?
i thought noir also meant gloomy
