Several years ago, my Number One Son suggested that "splendid" was the nicest word in the English language. I agreed, and I still haven't found a word I like better.
I subscribe to the RSS feed for Dictionary.com's Word of the Day because it often gives me a laugh or teaches me something. And when I need to kick back and relax for a few minutes, I play a game or two of Scrabble against a robot at Scrabulous.com. I don't often win, because the robot cheats by using some spellings that would make even the most "creative" first-grader blush with shame. And here's a funny thing: the robot is a poor loser. If you manage to win a game, it says something like, "The robot wins by -71 points."
What word games do you play?
