How to use pro bono

Pro bono is used primarily in legal and professional service contexts to describe work undertaken without payment, typically for charitable purposes or to serve disadvantaged populations. It carries an implication of professional responsibility and public service, distinguishing it from casual volunteer work. The term is somewhat formal and is more common in legal, medical, and business contexts than in everyday speech.
