N'ihi ọtụtụ ihe kpatara ya, a na-eche na ụdị athematic ga-akawanye nká, na ụdaume isiokwu bụ ihe ọhụrụ nke PIE n'oge: Athematic paradigms (ụkpụrụ inflection) bụ ihe "na-adịghị agbanwe agbanwe", na-egosipụta ablaut na mkpanaka mkpanaka, ebe a na-ahụ ihe ngosi isiokwu dị ka ihe dị mfe ma ọ bụ nhazi nke ụtọ asụsụ na ọnụ ọgụgụ.
