Yeah, but it's a silly-sounding word and makes any attempt at a serious dialogue with it nearly impossible. "But there are lots of words that sound weird to us, Gaffer, because it's a fantasy. You just have no imagination." No, not quite. The other "weird" names work because they are far enough out there. Youngling is just a play on the word "young." In fact, I agree with Scruffy. When Yoda said it in AOTC it didn't bother me, because I thought it was just an affectionate pet name that Yoda had for children. And, as an affectionate pet name, it sounds really weird when used in the context of murder and destruction. It'd be like someone mourning, "Oh no, they killed Go-Mer-poo!" And, no, that was not a death threat. Don't interpret it as so.
