personnel

The word 'personnel' entered English in the 19th century from French, where 'personnel' functioned as an adjective meaning "personal." The French term itself descended from the Late Latin 'personalis', which originated from the classical Latin 'persona', denoting an actor's mask, a character in a play, and eventually a human individual. The modern, specialized English meaning—the body of people employed in an organization—developed through military and bureaucratic usage, shifting from the adjectival sense of "personal (matters)" to a noun signifying the collective staff themselves. This evolution illustrates how a term for an individual ('person') can, through suffixation and semantic narrowing, come to represent an organized group within a professional context.

Structure: person (individual) + nel (noun suffix) - person: From Latin 'persona' (actor's mask, character, person). In this word, it functions as the base root meaning "individual human being." - nel: A suffix derived from the French diminutive '-el' or '-elle', which was added to form adjectives and later nouns. In 'personnel', it functions to form a collective noun referring to a body of people.
