Northwest Caucasian languages
Typical of Northwest Caucasian languages, Abkhaz is an agglutinative language that relies heavily on affixation. It has an ergative-absolutive typology, such that the subject of an intransitive verb functions identically to the object of a transitive verb. Notably, Abkhaz expresses ergativity entirely through the ordering of subjects and objects within verb constructions rather than through overt case marking as most other ergative languages do.
