Aghul phonology

Aghul has contrastive epiglottal consonants. Aghul makes, like many Northeast Caucasian languages, a distinction between tense consonants with concomitant length and weak consonants. The tense consonants are characterized by the intensiveness (tension) of articulation, which naturally leads to a lengthening of the consonant, which is the reason why they are traditionally transcribed with the length diacritic. The gemination of the consonant does not by itself create its tension, though morphologically tense consonants do often derive from adjoining two single weak consonants. Some Aghul dialects have an especially large number of permitted initial tense consonants.

Consonants

 * The glottal stop transcribed here is named rather ambiguously a "glottalic laryngeal" by the source.
 * Also note that the source names the epiglottal series ″pharyngeal″ indiscriminately in all the tables, also when it includes a plosive and thus clearly isn't a true pharyngeal.
