Digor Ossetic, and specifically the dialect characteristic of the Iræf district.
Description
The IE-CoR data are intended to represent the Digor dialect as a whole, hence its location set on Digora (Digorskij district), although transcriptions in particular reflect the dialect characteristic of the Iræf district, with non-phonemic palatalisation of affricates and sibilants before front vowels (cf. /cʼew/ [čʼew] ‘bird‘). This variety also appears to be currently more widespread than the one without palatalisation.
Note on geographical location
Digora, the largest Digor-speaking town of Ossetia and also roughly the centre of the modern Digor-speaking area. (The original Digor area was more in the highlands.)
