The word guttural literally means 'of the throat' (from Latinguttur, meaning throat), and was first used by phoneticians to describe the Hebrew glottal (?) and (?), uvular (?), and pharyngeal (?).
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. The journal Anthropos published a phonetic alphabet to be used in their articles (see Americanist Phonetic Notation), in which "guttural" included the velar and uvular consonants but not those further back.
The term is also commonly used non-technically by English speakers to refer to sounds that subjectively appear harsh or grating. This definition usually includes a number of consonants that are not used in English, such as epiglottal and , uvular [?], and , and velar fricatives and . However, it usually excludes sounds used in English, such as the velar stops and , the velar nasal , and the glottal consonants [h] and [?].
In popular consciousness, languages that make extensive use of guttural consonants are often considered to be guttural languages. English-speakers sometimes find such languages strange and even hard on the ear.
Examples of significant usage
Some of the languages that extensively use [x], [?], [?], [?] and/or [q] are:
In French, the only truly guttural sound is (usually) a uvular fricative (or the guttural R). In Portuguese, [?] is becoming dominant in urban areas. There is also a realization as a [?], and the original pronunciation as an [r] also remains very common in various dialects.
In Russian, /x/ is assimilated to the palatalization of the following velar consonant: . It also has a voiced allophone?, which occurs before voiced obstruents. In Romanian, /h/ becomes the velar [x] in word-final positions (duh 'spirit') and before consonants (hrean 'horseradish'). In Czech, the phoneme /x/ followed by a voiced obstruent can be realized as either [?] or [?], e.g. abych byl .
In Kyrgyz, the consonant phoneme /k/ has a uvular realisation ([q]) in back vowel contexts. In front-vowel environments, /g/ is fricativised between continuants to [?], and in back vowel environments both /k/ and /g/ fricativise to [?] and [?] respectively. In Uyghur, the phoneme /?/ occurs with a back vowel. In the Mongolian language, /x/ is usually followed by /?/.
The Tuu and Juu (Khoisan) languages of southern Africa have large numbers of guttural vowels. These sounds share certain phonological behaviors that warrant the use of a term specifically for them. There are scattered reports of pharyngeals elsewhere, such as in the Nilo-Saharan, Tama language.
