If you don't hear the final 't' of "chatte" you should definitely hear the final "ch" sound
This comment has already been debated at length in earlier threads.
It's a bit like the English word "❤❤❤❤❤" whose literal, original meaning is/was "a female dog". The meaning has obviously morphed since then.
Chat is pronounced like 'SHA' or something but chatte is pronounced like '❤❤❤❤'. You can hear the 'T' in chatte. I had difficulty distinguishing the difference at first but you'll get used to it :)
Now it's the female cat but i can't hear the difference between them.
I know well that it is derogatory or insulting to use La Chatte but it is also unfair not to let us know what it actually implies so that we can seriously avoid it knowing Why. It is like the West Indians and their "Raasclaat". They will never Ever tell a white person what it means yet between themselves they often use it. (Men only). If we are going to learn French, please let us Learn French!
I swear I can't hear the difference in mange, manges, manger and mangeon.
