Lezgic languages

Minor Lezgin sub-ethnic entities demonstrate a distinct convergence toward the standardized Lezgin literary language.^[1] Lezgin, Aghul, Rutul, Tabasaran, Tsakhur and Udi are literary languages. Khinalug may either be Lezgic or an independent branch of the Northeast Caucasian family.

The Lezgic languages are relevant to the glottalic theory of Indo-European, because several have undergone the voicing of ejectives that have been postulated but widely derided as improbable in that family. The correspondences have not been well worked out (Rutul is inconsistent in the examples), but a few examples are:

• Non-Lezgic: Avar tstsʼar; Lezgic: Rutul dur, Tsakhur do 'name'
• Non-Lezgic: Archi motʃʼor, Lak tʃʼiri; Lezgic: Rutul mitʃʼri, Tabassaran midʒir, Aɡul mudʒur 'beard'
• Non-Lezgic: Avar motsʼ; Lezgic: Tabassaran vaz 'moon'

A similar change has taken place in non-initial position in the Nakh languages.^[6]
