the.com/streetwalker

means A prostitute who solicits customers in public, typically on the street rather than through other arrangements.

from Straightforward compound of 'street' plus 'walker' — someone who walks the streets, specifically to solicit. The term dates to at least the 1500s-1600s in English, when 'walker' alone could already carry shady connotations, and pairing it with 'street' pinned down exactly which kind of walking was meant. The logic is literal: unlike a courtesan working from a fixed address, the streetwalker's workplace was the pavement itself, and her trade was advertised by the simple act of pacing it.
