Resumen: This article reviews the text and interpretation of some ancient evidence on the pronunciation of syllable coda m in Latin. Crucial textual emendations are suggested for passages by Annaeus Cornutus and Velius Longus, and the resulting evidence is reinterpreted in the light of current phonological theories. Some of the accepted views on the pronunciation of –m are challenged by highlighting the likely sound variation in neutralization contexts. The evidence from both grammarians and inscriptions reveals that the possibility of m sounding [n] in the internal preconsonantal position could have been more widespread than previously thought.
