Think Capital is a definite
Leaning Date myself as it was next in the list, Capital + Washington would be a simpler clue? Just any state capital - 2 would be an easy clue for Capital + Washington no?
Yeah Date has other pay connotations as well other than paying for a date.. pay day, payments due on certain dates, 1st of the month.. standing orders etc
I'm all in on Capital + Date let's see what irtm says
(And of course just to be even more sure the other word on the list is Block and Capital + Block is an easy letters - 2 clue)
EDIT: and if it's Date and Block then COCK - 2 would be a brilliant clue for that lol
