This spell grants the creature touched the ability to speak and understand the language of any intelligent creature, whether it is a racial tongue or a regional dialect. Naturally, the subject can speak only one language at a time, although she may be able to understand several languages. Tongues does not enable the subject to speak with creatures who don’t speak. The subject can make herself understood as far as her voice carries. This spell does not predispose any creature addressed toward the subject in any way.
