It is a very expressive language, able to convey tone and emotions."
Gotta say, that is REALLY dumb.
I'm not sure what you're trying to say here. Is it that the explanation is dumb, or the notion that the language is expressive and able to convey tone and emotions dumb?
For me, the linguistics training in me is screaming for something more explicit than "able to convey tone and emotions," and demands to know if those two things are the
limit to the language's expressiveness (besides, of course, its tactical uses). Tone and emotions are important, but there are other nuances that going into the ability to express, say, the notion of gods, morality, reasoning/logic, etc.
Also, I'll note that while I absolutely abhor the notion of the Baldur's Gate novels being considered canon (Abdel Adrian? Hrrghh....), and as wary as I am of encouraging the abundant RPing of Good Drow thanks to Salvatore's work, I
have to acquiesce to canon derived from his work, considering how prolific his writing is and how much it has strengthened the community's love for DnD. So I'd really love to get a clearer idea of what the line about DSL's expressiveness is supposed to mean.
My purpose here is just to get a firm understanding of the boundaries intended by the PotM team and then see those boundaries respected IG so we continue to maintain the quality RP we have.
