Maintain Your Brain Friday - Cryptogram

Cryptograms are secret code puzzles.

Cryptogram Example:
JGNNQ = HELLO.  The word was encoded by replacing each of its letters with the second letter after it in the normal alphabetic sequence.  J represents H (2 letters down), G represents E (2 letters down), N means L (2 letters down), and Q means O (2 letters down).  Thus, the hidden word is hello.
