Abstract
Augustine’s De Magistro, an early work, is cast as a dialogue between himself and his bright son Adeodatus. It leads from a discussion whether teaching is effected through signs to the conclusion that words are not a route to knowledge, unless the soul is taught by God, the only teacher. Although Augustine is mainly concerned to develop his new theory of signification, the dialogue is set in the frame of traditional grammatical teaching, which had become standard in later Roman antiquity. These elements of grammatical education make a good starting point for exploring what precisely was Augustine’s position within this system. Taking into consideration especially his definition of pronomen and the eight parts of speech we come to the conclusion that Augustine as a grammarian is dependent on Charisius and his teacher.
