Forms

Platōnicus (feminine Platōnica, neuter Platōnicum); first/second-declension adjective[1]

Etymology

It is from Latin Platō (“Plato”) + -icus,[1] corresponding to Ancient Greek Πλατωνικός (Platōnikós), from which Köbler and the DMLBS derive it.[1][2][3] The philosopher's name is Πλάτων (Plátōn).[4]

Earliest recorded meaning

The earliest instance the dictionaries give is in the Commentariolum petitionis ascribed to Quintus Cicero, where a Platonicus homo is a profound thinker.[5][6] Cicero speaks of the Platonici, the followers of Plato.[6][5]

Semantic evolution

Its main sense was “of Plato or his philosophy”; as a masculine noun it meant a follower of Plato, and the neuter plural meant Plato's teachings.[7][6] Augustine used Platonici of the Neoplatonists and Platonica of Plato's doctrines.[6]

Medieval British writers used it in the same senses, from Alcuin on.[3] Lorenzo Valla discussed it beside the rival formations Platonius and Platonianus.[8] English took it over as platonic in the 1530s.[9]
