Ok, so far, as a lover of letter games, I've found 37 different words (can you tell I'm not in the mood for work ? ) :
lazy, happy, impatient (patient), genuine, elegant, peaceful, reserved, witty, sentimental, lovely, dependent, loyal, lethargic, overdramatic (dramatic), talented, charismatic, honest, naive, kind, passionate, insecure, thoughtful, eloquent, restless, outspoken, outgoing, sweet, charming, courageous, compassionate, calculating, stubborn, understanding, polite, critical, caring, graceful...
I'm sure I'm missing a lot. Can't find anything spelled backward, isn't there any ?
