All the characters in my novel speak English, though they are different races. Not exactly races, since they're all human, but they do have different native tongues. There are times when they're speaking to each other that they throw out phrases in there native tongue, like threats or 'damnit' (except it would come out in there tongue, obviously). Now short, one word phrases wouldn't need to be translated, since I think the meaning is obvious, but a phrase like a threat or something. How would I write that in there so the reader knows what's being said without literally translating it?
