metier

The word 'metier' entered English in the late 18th century, retaining its French spelling and pronunciation as a sophisticated borrowing. Its journey begins with the Latin ministerium, meaning "service" or "office," which itself evolved from the concept of a minister or attendant—one who performs a subordinate function. Through Old French, the term broadened from a simple "need" or "task" to signify a customary occupation or trade. In English, it underwent a subtle refinement of meaning, shifting from any trade to specifically denote the work or activity for which one has a strong innate aptitude, thus capturing the notion of a true calling or natural forte.

The word is a direct loan from French, adopted as an unanalyzed whole into English. It derives from Old French mestier (service, occupation, need), which came from Latin ministerium (service, office), from minister (servant, attendant). The Latin root is minus (less) + the comparative suffix -teros, implying a subordinate role.
