Prostitution is sometimes described as commercial sex or hooking.
Another commonly used word for a prostitute is hooker.
Although a popular etymology connects "hooker" with Joseph Hooker, a Union general in the American Civil War, the word more likely comes from the concentration of prostitutes around the shipyards and ferry terminal of the Corlear's Hook area of Manhattan in the 1820s, who came to be referred to as "hookers".
Those offering services to female customers are commonly known as gigolos; those offering services to male customers are hustlers or rent boys.
