Meaning: to move to an earlier time; the opposite of postpone.
Usefulness: 1 ("Happy hour has been preponed to 4pm." "My meeting was preponed, so I'll be home early." "We need to prepone our next dinner - I have so much to tell you!")
Logofascination: 2 (Technically, we can also compone, depone, dispone, impone, interpone, oppone, propone and suppone; the pone is from the Latine ponere, meaning to put or to place. Apparently the stem for this was confused with the stem for pose, so we generally compose, depose, dispose, impose, interpose, oppose, propose and suppose instead.)
