Granted, there are also people who get annoyed when the game seems too accepting of unusual words, but if you can point them to a valid dictionary definition for that oddball word, they usually accept it without argument.
Definitely not any less valid or unsatisfying than "zebra".
Given that those two don’t have the same letters, isn’t that the expected outcome?
EARLS was not accepted, and I had already decided not to try REALS. (is there a rule against plurals?) what it was looking for was LASER which has a more tenuous claim on being a word than those two.
