From Proto-Italic *senkairos, from Proto-Indo-European *sem- (compare Latin simplex, and Sanskrit सम (sama, “whole, together”)) and *ḱer- (“grow”) (compare Sanskrit किर् (kir, “pour out”)). According to De Vaan, the second part of the compound derives from the unattested adjective *caerus found in the first part of caerimōnia, which is also related to caelum (“sky”). However, this is problematic: the expected outcome of Proto-Italic *senkairos would be *sincīrus, since Proto-Italic /ai/ gives /iː/, not /eː/ under vowel reduction (as in occīdere), and it is implausible that this word was imported from rural dialects of Latin which monophthongize /ai/ to /ɛː/, as in fēnum, without leaving any trace of the urban Latin development.
