Gurth's Word Game
Here are two lists of words:
(1) part, arm, fair, all, band, cloud, earl, hill, pearl, sill, powder, tall.
(2) total, leg, unfair, some, orchestra, sun, king, mountain, diamond, door.
These two lists represent two mutually exclusive categories. (Hint: spelling is of the essence in the definition of these categories. Not the meanings of the words).
The winner will be the first person to guess what the two categories are.
Each player may submit a total of 10 words, all together or not, and I will state which categories the words belong to (every word in English belongs to either category 1 or category 2.)
