Thanks. I used 'soundalikeness' because 'homophone' is full of connotations for me, it usually involves a gripe about the latest homophone, alleged homophone in the Times puzzle.
Yes, do write to the Times. I'm sure you could rattle off quite a few -ess words, supplying some clues would be good too. That could be a dual purpose move - maybe one of your clues will oust an SA/It clue. We can dream....
