on’yomi

Alternative spelling
硏究 (kyūjitai)

Etymology

From Middle Chinese 研究 (ngen *kiu^H?). Compare modern Hakka ngiên-kiu, Min Dong ngiĕng-géu, Min Nan gián-kiù.

The original on'yomi for the first character 研 was gen, more closely matching the Chinese origins. For reasons unknown, the reading shifted from gen to a kan'yō yomi of ken.
