I agree, some of them are unpronounced (mute is the right term) but needed especially when comes the writing or reading part otherwise you wouldn't be able to understand the words.Originally Posted by TATY
Here's an example, "col" and "colle" are pronounced the same way but have two different meanings.
And I agree also, French isn't a phonetic language but once you know the rules of pronounciation and I would say 'you read what you see', which is not the case in English for example.
