Abstract

The reason for the lexical transformation of classical Latin auctor and auctoritas into Neo-Latin author and authoritas has remained obscure outside of specialist literature. This note offers a consolidated account of the matter in English. Based on a minor misreading of Priscian’s Institutiones grammaticae by glossators active at the turn of the thirteenth century, a back-formation of Latin author by analogy with Greek αὐθέντης and αὐθεντία was proposed by humanist scholars in the sixteenth century. Once introduced, the Neo-Latin fricative th dropped out or was never fully adopted into any of the European vernaculars except English, where it nonetheless survives in ‘author’ and its derivatives today.
