Orcish

The language of the orcs and many of their close kin, called Orc or Orcish depending on the speaker. It's notable for having a high ratio of expletives and being extremely expressive despite having a somewhat limited vocabulary. Much of the flavor of the language doesn't translate well to writing, and few literary works are known to exist in Orcish. Unlike many languages, Orc doesn't have a "formal" tone; instead there's the "familiar" tone and the (much more commonly used) "vulgar" tone.
Speakers of Orc without significant tusks or similar mouth structures tend to sound a little off to natural speakers of the language (though this can be overcome with enough practice).
