Learing to pronounce French words is rather easy. English is a huge mess.

It’s usually (not always) clear how a word is pronounced in French if you know its spelling.
French (there are quite a few of them - think CA for example) has just as many idiosyncrasies as English when you really get in to it.
It is totally impossible to predict how an unfamiliar written word is pronounced in English, but quite easy in French (barring some ambiguous situations like if a noun ends in “s”.)
By the way, I don’t know what CA means. If you’re referring to the French word “ça”, its pronunciation is completely regular and predictable given the spelling.
