This page is one of a series listing English translations of notable Latin phrases, such as veni, vidi, vici and et cetera. Some of the phrases are themselves translations of Greek phrases, as ancient Greek rhetoric and literature started centuries before the beginning of Latin literature in ancient Rome.^[1]

This list covers the letter P. See List of Latin phrases for the main list.
