orcs and goblins- what's the difference???

[Thalion]

since ohobbits and men were originally we not interchange thier names all the time... Aragorn was a large hobbit that walked with long strides.

Aragorn was never a hobbit...TROTTER was a hobbit, and if I remember correctly, it wasn't Tolkien was finished with the tale that he basicaly realized he needed/wanted/should/discovered that Trotter was in fact Aragorn, and that he should be called Trotter.......additionally, Tolkien never says that hobbits became me or vice versa...although this is alluded to in the cartoon version of Return of the King...

As for Orc/Goblin...I suffice it to say that most of the preceeding entries have covered it
