Should the "s" be pronounced at the end of "plus" in this (positive) construction?

Bonjour Aaron,

The general rule is that s at the end of the French word plus is pronounced when it's positive, and not when it's negative. So,

J'ai plus de temps = I have more time = s is pronounced.

Je n'ai plus de temps = I don't have any more time = s is silent.

Thanks Laura! However, I'm afraid that perhaps I wasn't specific enough — I didn't realize my question would be posted on a separate page without the full context of the exercise that gave rise to it. My question was concerning the *plus [clause] plus [clause]* construction, which I did think might fall under the general rule, but since I posted it, I've read conflicting answers elsewhere. Some suggest that the *s* is not pronounced in this context, and some say that in this context both ways of saying *plus* are heard.

Rebonjour Aaron,

Sorry about that. In certain expressions, including plus __ plus ___ and de plus en plus, pronouncing the s at the end of the plus is optional. (Unless of course there's a required liaison, as in de plus en plus.)

Great, thanks again Laura!
