16 down. Clue: Painful rash on the bottom after chap sits in grass (8). I have: ?C?T?I?G. I think it must be SING (grass) round C?TH which leaves SCATHING or SCYTHING but can't see the word play. Help please.
I think 'scything' has a similar definition and is therefore a candidate. I share your dilemma Vimto as I think either would fit. 'CYT' (the 'rash' part of the clue) may be the rest of the clue, but I'm unsure.
