A woman who provides sexual services, often to wealthy or high-status men, and may also offer companionship or entertainment.
In historical times, a courtesan often held a significant social position and was well-educated.
Courtesan → It is derived from the Italian word 'cortigiana', which comes from 'corte' (meaning court) and the suffix '-ana' (indicating belonging to). A courtesan originally referred to a woman who belonged to the court, often serving as a companion or entertainer.
Think of a woman who is part of the 'court' ('corte') — that's why a courtesan is associated with the court and its social life.
