Yeah I'd never have got that but I probably should check scrabble sites rather than dictionary ones for words like that, most don't list many 5 letter words ending with that letter.
Never heard of 13D before dunno why. I probably would have got 19A eventually though.
Too many obscure words for me, usually if I use a thesaurus I at least go "oh of course" when I find the answer, but not for this one.
It was made up for by 12A though which was my COD.
