I recently watched the LOTR trilogy and I couldn't help but be distracted by a certain subject that has been plaguing me ever since I first saw the trilogy.
I've always been a bit confused by all the different types of orcs, goblins and trolls. I can tell Uruk-hai from orcs, and cave trolls/trolls in general, but whenever it comes to goblins, and mordor orcs, and isengard orcs, and just plain orcs in general, I tend to get a bit confused.
For example, in FoTR when the nine first enter the mines of moria and find all the carnage and dead bodies left over from the dwarves being attacked, Legolas pulls out a random arrow from a body and exclaims, "Goblins!"; while later when Pippin pushes a certain rather noisy skeleton down the well and they start hearing drums, Legolas exclaims, "Orcs!"
That bit is mixed in with the orcs/uruk-hai that capture merry and pippin, and the orcs that captured frodo after he was poisoned by shelob, and all the other orcs in the different battles that are really starting to make my head spin!
So after all my rambling (
), the main question is: Is there any real difference between different breeds of orcs, goblins, and trolls besides where they were 'created' so to speak, and if there are, what are they?
Any input you could give me would be most helpful!
