I would like to see "atopic" added to this puzzle/combination of letters. "Atopic" is a noun and adjective that is also in Scrabble's dictionary and refers to a type of allergy. Merriam Webster counts it, and they consider it an adjective as well that is from the Greek words "atopia" and "atopos," both of which refer to something uncommon (in the case of "atopic," it's a referent to genetic disposition to develop an allergy). I think it would be as allowable as a word like "ectopic" (another adjective referring to a medical condition, like an ectopic pregnancy). Neither are proper nouns. Thoughts? Thanks!
