IPA: //ˌeɪpiˈɔrnɪs//
KK: /ˈeɪpiˌɔrnɪs/
A type of very large bird that could not fly and lived in Madagascar a long time ago.
The aepyornis was one of the largest birds to ever exist, towering over its contemporaries.
Aepyornis is derived from the Greek roots "aepy" (from "aepus", meaning high or lofty) and "ornis" (meaning bird). The word refers to a bird that was notably large or high in stature, specifically the extinct elephant bird of Madagascar.
Imagine a bird that is 'high' ('aepy') and 'lofty' — that's why 'aepyornis' refers to a very large bird.
