Sunday Puzzle

It's Sunday again, and you know what that means—time for me to rip off the puzzle segment from NPR's Weekend Edition Sunday!

Mustachioed enigmatologist

extraordinaire, Will Shortz

If you're a newcomer, each week on Weekend Edition Sunday, Will Shortz (the hardcore crossword puzzlers' almighty God) comes on the radio to do three things: share the solution to the previous week's puzzle, invite a winner who entered the correct answer to play another puzzle (usually word-related) on the air for word-nerdy prizes, and present everyone with the next week's puzzle (answers due in by Thursday afternoon via the WES website if you want a chance to play on the air).

Note: I never post the solutions on this blog…at least not before the submission deadline. I see lots of keyword traffic coming from people looking for the answers, which is at best impatient, and at worst, cheating. For shame.

Now without further ado, here's this week's new puzzle:

Think of two five-letter words that are exact opposites, in which the first two letters of each word are the same as the first two letters of the other, only reversed. Hint: The fourth letter of each word is A. What two words are these?
