I got the word BAITH on like turn 5, and I only chose that because I couldn't figure anything out. I thought it was a nonsense word. But mixing in a scottish slang word in the easy section was a surprise.
My wife missed that word, and it said the correct word was “habit”.
I also did “baith” (for the same reason as OP), and ended up making it to 16, but I feel like I shouldn’t have, since I’ve never heard of “baith”. I was confused when it accepted it.
