• “genius” in Kamus Besar Bahasa Indonesia, Jakarta: Agency for Language Development and Cultivation – Ministry of Education, Culture, Research, and Technology of the Republic of Indonesia, 2016.

Ultimately from Proto-Indo-European *ǵenh₁- (“to beget”), perhaps through Old Latin genō (“to beget, give birth; to produce, cause”), +‎ *-yos; compare Proto-Germanic *kunją (“kin”) and Sanskrit जन्य n (jánya, “lineage, tribe, people”), though all probably independent formations. Comparisons with Aramaic ܓܢܝܐ (ginnaya, “tutelary deity”), and with Arabic جِنِّي (jinnī, “jinn, spirit, demon”) and جَنِين (janīn, “embryo, germ”), suggest the effects of an older substrate word.
