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".
Clients of prostitutes are sometimes known as johns or tricks in North America and punters in the British Isles.
These slang terms are used among both prostitutes and law enforcement for persons who solicit prostitutes.
Most sex worker activists groups reject the word prostitute and since the late 1970s have used the term sex worker instead.
However, sex worker can also mean anyone who works within the sex industry or whose work is of a sexual nature and is not limited solely to prostitutes.
In this sense, "prostituting oneself" or "whoring oneself" the services or acts performed are typically not sexual. In 2007, a Russian caricature depicted the Baltic states as three "ladies of the night", "vying for the attentions of Uncle Sam, since the Russian client has run out of money".
It is sometimes referred to euphemistically as "the world's oldest profession" in the English-speaking world. Brothels are establishments specifically dedicated to prostitution.
