It is a simple noun - a person who is Jewish is a Jew. I don't think it is inherently derogatory although used that way by some.
Lots of words that are used derogatorily are in Lex (SOWPODS). I agree it feels weird to play them, but - it's a word game.

I love that the definition of the most recent word played shows up below the game on my laptop. But it has stopped showing up recently. Is there a way to fix that in my game settings? I have searched but not found a way. Thanks.

@lexulous Thank you! It's good to know you are listening. I want to emphasize that I like a lot about the newest revisions - the definition is there, for example. And I just noticed that the % of unseen tiles that are vowels is also visible. Pretty good additions!
I just wish I had spelled TILES correctly in my headline - for a word game, augh!!!

@dan-mitchell I love it! Thank you! Just started learning my away around more than just the playing board here on Lex...I appreciate your help.
