What is the definition of a prostitute?

The definition of a prostitute specifically refers to someone who engages in sexual activities with others in exchange for money. This definition emphasizes the act of providing sexual services as the primary function of prostitution. The focus is on the sexual aspect, which is distinct from the other roles mentioned.

In contrast, while providing companionship for money may seem similar, it does not necessarily involve sexual activities, which is a key element in defining prostitution. The reference to performing in plays or working in adult films, while related to adult content, does not align with the standard definition of prostitution, as they do not inherently involve direct sexual transaction with clients for money. Thus, the definition of a prostitute is most accurately captured by the answer that highlights the sexual services exchanged for financial compensation.
