historical usage of primary
The English adjective primary is a direct borrowing from the Latin adjective prīmārius “very important, leading, chief, excellent, first-rate.” Prīmārius is a pretty obvious derivation of prīmus “leading, foremost, furthest out, extreme, earliest, first” and the adjective and noun suffix -ārius, the ultimate source of the English suffix -ary. Prīmus is formed from the Proto-Indo-European root per, which has many modifications and extensions, and whose fundamental meaning “forward, in front, through” is the base of many adverbs, prefixes, and prepositions. Variants of the root per appear in the Latin prefix, adverb, and preposition prae-, prae “in front, ahead” (adopted as pre- in English) and prō-, prō, implying forward motion, making an opening, priority in time or importance (source of English pro- ). Variants of per appear in Greek prōtos “first” (as in English protein and proton ) and in Germanic (Old English) forma, formest, forth, furthra, fyrst (English former, foremost, forth, further, first ).
