Word Origin for prime
late 14c., "first in order," from Latin primus "first, the first, first part," figuratively "chief, principal; excellent, distinguished, noble" (source also of Italian and Spanish primo), from pre-Italic *prismos, superlative of PIE *preis- "before," from root *per- (1) "beyond, through" (see per).

"earliest canonical hour" (6 a.m.), Old English prim, from Medieval Latin prima "the first service," from Latin prima hora "the first hour" (of the Roman day). Meaning "most vigorous stage" first recorded 1530s; specifically "springtime of human life" (often meaning ages roughly 21 to 28) is from 1590s. In classical Latin, noun uses of the adjective meant "first part, beginning; leading place."
