List of Latin phrases

For thoughtful child sponsors
This page includes English translations of less common Latin phrases (i.e., not always found in dictionaries), some of which are themselves translations from Greek.

For a list of more formal proverbs, see: List of Latin proverbs. Note that the difference between phrases and proverbs is often subjective. Please use this test to see whether a Latin sentence is a phrase or proverb: If the sentence is an old yet common saying that expresses some practical truth, then it is probably a proverb. If it is in the form of an incomplete sentence or does not contain some practical truth, then it is probably a phrase.
