Linguistic Origin & Historical Etymology

Derived from the combination of 'public' (from Latin 'publicus', meaning of or belonging to the people) and 'domain' (from Old French 'domaine', from Latin 'dominium', meaning property or ownership). Originally referring to land owned by the state, the term expanded in the 19th and 20th centuries to intellectual property no longer protected by copyright.
