Kajtak, Kubachi, Itsari, Mehweb and Chirag are often considered dialects of the same Dargin/Dargwa language.
[4] Due to the linguistic fragmentation of the Dargin langiuages, speakers use Russian as a lingua franca.
The source is rather ambiguous in its using the term "laryngeal" for a presumed column of consonants that includes both a "voiced" and a "glottalized" plosive.
A voiced glottal plosive cannot be made, because the glottis needs to be closed, and an ejective consonant requires an additional closure further up the vocal tract.
Pending clarification, this row has been transcribed here as an epiglottal column and a glottal stop, both found in many other East Caucasian languages.
