To make his living, Demosthenes became a professional litigant, both as a "logographer" (, ), writing speeches for use in private legal suits, and as an advocate (, ) speaking on another's behalf. He seems to have been able to manage any kind of case, adapting his skills to almost any client, including wealthy and powerful men. It is not unlikely that he became a teacher of rhetoric and that he brought pupils into court with him. However, though he probably continued writing speeches throughout his career, he stopped working as an advocate once he entered the political arena.* G. Kennedy, "Greek Literature", 514.</ref>
