Guttural

In phonetics, the word guttural is an imprecise term that can be used to refer to any place of articulation in the back of the throat, e.g. velar, uvular, laryngeal, epiglottal, etc. Laymen in particular often use this word with connotations of a subjective 'harsh' or exotic quality. In sci-fi or fantasy works, characters may describe an in-world language (such as Klingon in Star Trek) as 'guttural' to emphasize how exotic it sounds.
