Bzyb (also spelled Bzyp) is a major dialect of Abkhaz, native to the Bzyb River region of Caucasus.^[1]

It differs from standard Abkhaz mainly in terms of phonology. It shares the [ɕʷ] and [ʑʷ] sounds with the Sadz dialect, and the [t͡ɕ], [d͡ʑ], [t͡ɕʼ], [ɕ], [ʑ], [χˤ], and [χˤʷ] sounds are unique to Bzyb. Standard Abkhaz (which is based on the Abzhywa dialect) lacks these sounds.

The Bzyb consonant inventory appears to have been the fundamental inventory of Proto-Abkhaz, with the inventories of Abzhywa and Sadz being reduced from this total, rather than the Bzyb series being innovative.
