In the time of the late Republic, an ōrātor like Cicero would give all sorts of speeches. And some of his most famous are either attacking or defending someone on trial.
Was there a Classical-era word for someone who did this specifically, narrower than the general ōrātor? In other words, some equivalent to our modern "lawyer" (or even narrower "prosecutor" or "defense attorney" perhaps)?
Lewis & Short's patronus entry gives some options used by classic authors:
II. Transf., a defender before a court of justice, an advocate, pleader (syn.: advocatus, causidicus, procurator, cognitor): judicis est semper in causis verum sequi, patroni nonnumquam verisimile, etiamsi minus sit verum, defendere, Cic. Off. 2, 14, 51; id. de Or. 2, 69, 280: patronus alicui causae constitui, id. Mur. 2, 4; cf.: his de causis ego huic causae patronus exstiti, id. Rosc. Am. 2, 5; Lex. Servil. lin. 9: patronus partis adversae, Quint. 4, 1, 11; cf.: patronus adversarii, id. 4, 1, 11; Tac. Or. 1.
