词源 1
From Middle English prime, from Old French prime and its etymon, Latin prīmus (“first”), from earlier prīsmos < *prīsemos < Proto-Italic *priisemos, ultimately from Proto-Indo-European *per- (“beyond, before”). Doublet of primo and primus.
The noun sense "apostrophe-like symbol" originates from the fact that the symbol ′ was originally a superscript Roman numeral one.

Related to primage and Latin prīmus.
词源 3
From French prime (“reward, prize, bonus”).
