salesperson
UK: ˈseɪlzˌpɜːs(ə)n | US: ˈseɪlzˌpɜːrs(ə)n
n. a person whose job is to sell products or services
The word "salesperson" is a compound formed in Modern English by combining "sales" (derived from Old English sala, meaning "act of selling") and "person" (from Latin persona, meaning "human individual"). The term reflects the occupational role of an individual engaged in commercial transactions, emerging in the 19th century as retail and trade professions became more formalized. The structure logically merges the function ("sales") with the agent ("person").
