Re: Quick Fire Questions (A Place to Ask and Answer)
Is it a kind of noise made a the back of the throat without opening the mouth, like a unvocalised "Huh"? (Not to be confused with a "Hrumph" noise made by old Colonels in Victorian melodramas, since it's higher pitched, and with a sardonic, mordant edge.)
If so, then I've used "grunted" before and couldn't find anything better. If you want to be long-winded it could be "part-laugh, part grunt" but I can't easily get a verb out of that. If it's a real laugh, then "laughed without amusement" or "with an edge of..." whatever.
HB: Yes. Stop at once.
