@Michael Gaobest ETA is a Greek letter that is one of four that rhyme with each other, the other three are beta, zeta, and theta.

@Grant yeah the OMG in the clue is what made me think SAMESIES pretty quickly but I guess I’m just the right demographic to have samesies in my vocabulary even if I would only use it sort of jokingly.

@Erin yes this was really fun! The theme actually became apparent to me relatively quickly and I solved it in about half my average time for Thursday, and without help either, high five us!

@Steve Daniel I think it's correct, crossword clues like this can be tricky with no context, but it made me think of the biblical phrase, "he rent his clothes" = "he tore his clothes"

@Alex I was also bending over backwards to figure out why PROST didn't fit there as that's the form I've generally heard as well. I found this <a href="https://german.stackexchange.com/questions/27187/what-is-the-difference-between-prost-and-prosit" target="_blank">https://german.stackexchange.com/questions/27187/what-is-the-difference-between-prost-and-prosit</a>

@Jim in my experience Ser is only found in George R. R. Martin’s books and there it’s only used for knights, but it really had me wondering because I’d never seen bocce spelled with an i, but after changing it I got the puzzle right and found the Wikipedia that said bocci was a variant, who knew!

@Jerod pretty straightforward use of this definition I thought <a href="https://www.merriam-webster.com/dictionary/the%20nub" target="_blank">https://www.merriam-webster.com/dictionary/the%20nub</a>
