So I was looking through your profile, and I saw that you were making a version of Black Speech! That's really cool to hear, as I am also attempting something along those lines. Do you have the grammar and words down already? I'd like to see some examples! Thanks in advance!
Grammar rules are either in my head or not thought-up yet, I do have a few words. This is my first ever attempt at making a language, so I'm doing a lot of revising and arguing with myself about it.
I have a few examples that'll almost definitely be changed next time I read through the document I've made.
"Ronkbûr-hu Targhor-hai isha!" To the Black Pits with the (Men of Númenórean descent)!
"Goruth gushath gazum-igun Naghbûr-ina!" Your flesh shall burn under the heat of the Black Hand!
"Kûn Targhor-hai na lat-gur. Ûkûn Uruk-hai na lat-kûl!" The first version of this was a very clumsy translation of one of Gothmogs lines in the films (The age of Men is over. The time of the Orc has come!) that I've revised so much I should probably scrap it until I've fleshed out the language more.
Also, there's the Black Speech on my signature that I never use
I think goblins are differnt from orcs, as a sub-breed. Why? bc Gandalf refernces 'trolls, orcs, and goblins'. If goblins were just a diffrnt name for orcs, would'nt that mean he said trolls, orcs, and orcs?
Ah, I've seen this argument before. Correct me if I'm wrong, but it sounds like you're paraphrasing (not that it's important). There is a quote like that (maybe several, I'm not certain), but as far as I know, it only occurs in the Hobbit.
LotR is generally considered to be the most canon book in Tolkien's work. If something contradicts it (Goblins and Orcs possibly being considered seperate in the Hobbit), you should always refer to LotR for the right answer Azog the "Goblin" in the Hobbit is referred to as a "great Orc" in the Appendices. The band of Goblins led by Golfimbul is remembered as Bandobras Took fighting off an Orc raiding-party.
Now, let's look at the use of Goblin in LotR: while some people consider "Goblin" to refer to smaller or weaker breeds of Orcs, especially those who dwell in mountains, this is definitely not the case. Grishnakh is called a Goblin at one point. While Grishnakh is noted as being short, he's also noted as being broad, and possessing great strength; what's more, he comes from Mordor, not the mountains (straight from Barad-dur, in fact). Frankly, Grishnakh isn't the best example. A better one are the Uruk-hai: a pile of dead Uruks from Isengard, as identified by Aragorn, Legolas, and Gimli, are referred to as Goblin-soldiers. Here we can see that Goblin as a name doesn't apply only to shorter Orcs of Mordor (Grishnakh), great possible Half-breed Orcs of Isengard (Ugluk and Co.), or even the huge Orcs of Moria and Gundabad (Azog and Bolg).
Tolkien thought for a while, mainly in his very early scripts, that Goblins and Orcs might be separate. Maybe even while writing the Hobbit. But by the time of LotR, that information was rendered incorrect. In fact, here's a note at the beginning of my edition of the Hobbit:
"Orc is not an English word. It occurs in one or two places but is usually translated goblin (or hobgoblin for the larger kinds). Orc is the hobbits' form of the name given at that time to these creatures, and it is not connected at all to our orc, ork, applied to sea-animals of dolphin-kind."
While I did say that the Hobbit is slightly unreliable, this note was written years after it was originally published.
EDIT: Additional note, while I can't find a copy of it at the moment, there is apparently a letter where Tolkien confirms they are the same, if you needed any more proof.
Tough one, really. Some people think they exist, others think they're just a poetic exaggeration (which can also be attributed to sentences like "Orcs, Goblins, and Hobgoblins") for the storm the company was in.
Personally, I'm fine with both those interpretations. I don't like imagining them as Trolls, as some people do.
