Weighing into the debate on what is a common word, chavez sent the following from the website, without providing an email address:
Today: betel is a common work but not embattle. I would disagree with this.
Great game!!
Chavez, if you're reading this, you may be right - not just on saying Chihuahua is a great game, but on the relative commonness of the two words. At least the players found it so - 71 found "embattle", but only 52 found "betel".
As mentioned in other topics, I'm keeping in mind the possibility of fine-tuning the grouping of words into the common and rare categories.
