Morning all. Last one in - just need to put my mind to rest as I had to cheat using crossword solver to fill in the gaps, giving me a word I did not know...
10 A letter describing numbers having entered compound (9)
I've got a word which, working from the inside out, parses as
abbreviation for numbers + in, inside a letter (or, more commonly, a river), with an A at the front?
Does this fit with the consensus?
