Pro bono, short for pro bono publico , is a Latin phrase that means "for the public good." It refers to professional work undertaken voluntarily and without payment. While it traditionally referred to the provision of legal services by legal professionals for people who are unable to afford them, it is now used to describe specialist services provided by any professional free of charge to an individual or community. This can include legal services, as well as services provided by professionals in fields such as medicine, architecture, and finance
