}General chapter: Phonology
Lateral obstruents are a significant feature of Avar, Andic and Tsezic languages, as well as the Lezgic language Archi. In most cases the lateral system is represented by a fricative ɬ and two affricates tɬ and tɬ’ (in addition to l, which is present in all languages of the sample. Sometimes the subsystem is even more elaborate due to the presence of geminates.
The inventory of lateral obstruents can differ from 1 (Tsova-Tush, ɬ) to 12 (Akhvakh, ɬ, tɬ, tɬ’, each of which have a geminate, labialized and geminate labialized counterpart).
