Definition: Literally this adjective means “before the flood”.  Metaphorically it refers to a person or thing that is so old it has been around since the time of the flood or Noah’s Ark.  In other words, it refers to something extremely outdated.

Pronunciation: an-tee-di-loo-vee-an


This word is a compound of two Latin words.  “Ante” means before, and “diluvian” is from “diluvium” which means flood.  It was a word created by English physician Sir Thomas Browne in the 1680’s.

 Why this word?

In a culture where so much emphasis is placed on the latest, newest item or fad, it can be important to take a moment to remember the importance of history.  Newer does not always mean better, but older doesn’t always mean better either.  The word antediluvian reflects those aspects of history that it might be better to leave behind rather than to preserve, much as the Flood wiped out the parts of the earth that God did not deem worthy of preservation in the story of Noah’s Ark.  A prime example of this for me would be antediluvian notions about gender and racial equality.


How to use the word antediluvian?
