What does auspex mean?

An auspex was an Ancient Roman official who acted as soothsayer or priest and was responsible for interpreting omens to guide decisions.

The plural of auspex is auspices.

The Ancient Roman auspices were highly respected religious officials. They were consulted by lawmakers and other leaders prior to major events such as wars and the founding of colonies.

The word augur can mean the same thing, and it is also used as a general term for any prophet, oracle, or soothsayer.

Example: The emperor was known for never taking action before consulting the auspices.

Where does auspex come from?

The first records of the word auspex come from the 1590s. It comes from the Latin auspex, meaning “bird watcher” or “soothsayer,” from avis, “bird,” and specere, “to look.”

The Roman auspices formed many of their predictions by interpreting the flight patterns of birds. The related word auspice means “a favorable sign” or “a divination or prognostication, such as from observing birds.” This is where we get the adjective auspicious, meaning “favorable” or “fortunate.”

The related word haruspex refers to an Ancient Roman soothsayer, especially one who interpreted the entrails of animals.
