Latin Quotes Worth Knowing

Here is my collection of important Latin quotes. Memorizing these has been very valuable for learning the language. I have tried, wherever possible, to locate and include the actual reference to where these appear in ancient texts.

Ab ovoFrom the eggUsed to describe excessive detail in storytelling.
