In the 3rd or 4th cent. text Appendix Probi we find the line: digitus non dicitus "[the word for 'finger' is] digitus, not dicitus." The author's spelling correction proves how the word was pronounced by common speakers, and offers a rare glimpse of the evolution of Latin into Romance languages such as Spanish.
