I began to study French. I think it is a pretty good language. However, I am confused about some special pronunciation rules. E. g., pronunciation of S in words "disent" and "lisent". Does it sounds [s] or [z]? (I think it can be [z], because it is between two vowels even if E is silent. But I'm not sure.)
The 's' is pronounced [z] in these cases because it is between two vowels but you should be careful because there are a few exceptions.
They are relatively easy to spot if you are able to detect that the word is a concatenation of a prefix (or another word) and a word that starts with an 's', e.g.:
- désolidariser (but désolé = [dezɔle])
- dysenterie (but dysurie, an exception in the exceptions…)
Note that the word abasourdi is very often mispronounced by native French speakers with an [s] while it must be pronounced with a [z].
