Alongside the other case declination endings, the origin of the Ablative Case singular -է (-e) and the Ablative Case plural -ց (-ts) gave rise to dispute. The author analyses this phenomenon through a typological comparison of a number of Indo-European languages and uses a systematic approach to argue that: a) the prototype of the Ablative Case declination ending -է (-e) is the Indo-European diphthong endings *(-oi>)ei of the Dative Case, b) the -ց (-ts) declination ending of the Ablative Case plural has developed from the Hittite plural forms in analogy with the Genitive-Dative (Ablative) Case -š ending, c) the prefix (with ի - (i-)) formation of the Ablative Case emerged during the independent development of the Armenian language in the phase of Krapar to differentiate it through its form from the Genitive-Dative.
