Kaitag (Kaitag: ; also Kaidak, Karakaitak, Karkaidak, Qaidaqlan and Xajdak) is a Northeast Caucasian language spoken in Dagestan, Russia. It has sometimes been considered a divergent dialect of Dargwa due to it being part of the Dargin dialect continuum. The Routledge Ethnographic Handbook (2017) divided Kaitag into two dialects: northern (Magalis-Kaitak) and southern (Karakaitak). Recent results of the Association of the Russian Sociolinguists (2021) further developed it into three dialects: Lower Kaitag, Upper Kaitag and Shari, the latter of which may be a separate but closely related language.
The languages consists of eight varieties, forming three dialects. Each of the Upper varieties corresponds to a historical province of the region.
Consonants form by series of voiced, aspirated, fortis, ejective, and labialized variants. The palatal fricative [ç] might be the voiceless post-palatal fricative, which can be more precisely transcribed as [çà] or [xÃÂ].
The Kaitag language is usually written in the Cyrillic script. The letters of the alphabet are (with their pronunciation given below in IPA transcription):
Most of Kaitag's vocabulary stems from proto-Northeast-Caucasian roots. Like with other languages of Dagestan, there is a considerable number of Arabic, Iranian, Turkic and recently Russian loanwords.
