OK, you all ready to hear my crazy theory about gnomes? Of course you are. Here it is: gnomes aren't really a race. Gnomes are two sub-races.
The first gnomes are a sub-race of dwarves with an emphasis on mechanical prowess and tinkering. They still live underground but beards are optional. Call them 'tinker dwarves'.
The second gnomish sub-race are actually a sub-race of elves. They're mischievous and their small size means they prefer evasive tactics to direct combat. They live in the forest near their larger kin. They're 'little elves'.
There you go. Two separate sub-races... although perhaps they share a common gegnome.
Two sub-races? How about three or four or five or six?
We already have the "glammer-gnomes" (illusionists) and "tinker-gnomes" (artificers). In addition, weren't there some "whisper-gnomes" at one point? (And even "deeper-gnomes" in the form of the svirfneblin?)
And what about the "flatter-gnomes," who specialize in flattery, and who tend to become bards? What about them, eh?
(Alright, I made up those guys. . . .)
