@mistertoad my guess would be that English (or maybe "english") is acceptable as a word in certain games (in billiards one can "put some english" on a shot). Similarly, graphic artists use india ink, and when guests come over I bring out the good china: turning proper nouns into common ones! (of course I do still frequently see words being accept in the game when I had assumed they would be disallowed because of capitalization issues...)
