Common IS English
Just as Elvish is Welsh, Dwarves speak with a bad Scottish accent and Orcs speak German. And the Fey - they speak French of course!

Don't insult my mother tongue! Not all of us speak like brutish grunts! (as a side note, to "grunz" is actually doing pig noises so... yeah)
But to be honest, my Fey character does speak with a slightly french sounding accent... I simply wanted to emphasize the vowels, but she turned out to be quite the frankophone
