I am wondering if anyone can tell me what Goblins are? The Tolkien Companion defines Goblins as Orcs. Orcs being called Goblins by the Hobbits. I don’t recall any mention of the origin of goblins in The Silmarillion. In The Hobbit, Gandalf refers to the Misty Mountains as being full of Goblins, Hobgoblins and Orcs - presumably each being different entities. Can anyone clarify, please? Thank you!
