Interesting. I don’t generally play words that I know cannot be the answer (i.e. what I call “Scrabble words.”) So, for me, no. But those are interesting ones. I would never even have thought to try “rownd” as a possible valid word.
ETA: Wait – I thought you were joking at first, as I tried out “rownd” and it was not a word in any dictionary I could find, but “pronk” was. So, where did you find “rownd”?
Yeah, the only thing I could find was in wiktionary, where it claims it as Welsh. Fun word. It’s not even in the official Scrabble words dictionary or the tournament word list, but it is in SOWPODS (I forget what it stands for), so pretty darned obscure and I’m surprised it’s allowed.
