Guttural consonant

Guttural speech sounds are those with a primary place of articulation near the back of the oral cavity. In some definitions, this is restricted to pharyngeal consonants, but in others includes some velar and uvular consonants. Guttural sounds are typically consonants, but some vowels' articulations may also be considered guttural in nature.

Although the term has historically been used by phoneticians, and is occasionally used by phonologists today, it is now more common in popular use as an imprecise term for sounds produced relatively far back in the vocal tract. The term continues to be used by some phonologists to denote laryngeal consonants (including uvulars), as well as murmured, pharyngealized, glottalized, and strident vowels.

The word guttural literally means 'of the throat' (from Latin guttur, meaning throat), and was first used by phoneticians to describe the Hebrew glottal [ʔ] (א) and [h] (ה), uvular [χ] (ח), and pharyngeal [ʕ] (ע).

The term is now commonly extended to include also velar consonants, which deviates from the strict etymology. As used in linguistics, such a definition includes all velar consonants, regardless of manner of articulation.
