Anti comes from the Greek and means “against or opposed to.” It can also sometimes mean “preventing, reversing, or the opposite,” usually with a negative meaning. Many words use the prefix anti, including antiaircraft, antibacterial, antigravity, anticlimax, antiwar, and antihero.
Ante comes from the Latin and means “before or preceding,” for example, antechamber, antecedent, and antebellum. Not many words use ante. So where did the gambling phrase “ante up” come from? Well, if you want to play, you have to put your money in the pot before the game starts.
A few other words begin with ante or anti in which they are not used as prefixes. For example, antelope, antenna, antique, and antic. When we dig deeper, we find that antique does come from the Latin ante, meaning “before,” here before current times. Also, the word antic comes from anticus, meaning “very old and grotesque.”
Only one time do we separate any of these prefixes from their root words. This exception is A.M., or ante meridian, i.e., morning or before noon when the sun is at its meridian or highest point in the sky.
How about that prefix anto? That’s a very lonely prefix. The only commonly used word that uses anto is antonym, a word that means “the opposite.” Common antonyms are fat/thin and good/bad. Anto originally came into English from the Greek anti.
As for auntie, that word comes from the Latin word amita and the French tante. I had eleven aunts.
