I practiced French speaking on Busuu.com and they repeatedly failed me for the pronunciation of 'ç'.
I was asked to speak out loud the sentence
Elles sont françaises.
The feedback was 'It seems you had trouble with "françaises". The "ç" is pronounced like an "s".'
I thought the pronunciation of ç was almost the same as that of 's'. How can I differently and correctly pronounce ç in "françaises"?
