means A person whose job is to persuade others to buy goods or services, usually working on behalf of a company for commission or wages.

from Straightforward compound English: 'sale' (from Old English 'sala,' rooted in Old Norse 'sala,' meaning the act of selling) plus 'man,' the generic agent-noun suffix once used for any worker regardless of gender. The pairing shows up as the trades professionalized in the 1800s, when selling stopped being just something shopkeepers did and became its own specialized role — the traveling salesman, with his sample case and patter, became a stock figure in commerce and, later, in folklore and jokes.
