No no no no no. The Goblins and the orcs were the same things, though Orcs, while literally meaning the same as Goblins, were usually used more for Uruks, being the Orcish word for Fighters. There were Uruks and Slaves. The word Goblin, by process of elimnation, was more often used for the smaller, less powerful 'slaves'.

The Uruk-hai were not bred from Men, but were created by Sauron (not Saruman as in the movie). They were fearsome, mighty fighters, able to match a man one on one and win, and even able to take a fair swipe at Elves. They were also smarter than the Orcs, which was not shown in the movie. The Half-Orcs were rarely described in the LoTRs, but they were bred to be fast and easily deployable, but being both of the war like race of the Dunlending and the horrible race of the Orcs they could hold their own in battle.

Also Orc is the High-Elven (Quenya) word, derived from the Noble-Elven (Sinder) Yrch, which is in turn derived from the Orcword Urúk, and Golbin is the Mannish word (hence the Hobbits using it more). Also a Uruk-hai (High Orc or High Fighter) is a Hobgoblin. Does anyone know if Hob means High or something like that?

Hope this is useful, if i have made any mistakes please tell me cause it means by perception of ME is wrong.
