I've still got 4d to go here, though it has been a slog.
In the four or five years I've been doing the prize crossword this is the least enjoyable 'normal' puzzle. Maskerade's double grids with single clue efforts are the only ones I'd rank as worse.
I am not convinced 15a is actually a word. Has anyone checked it out in the Chambers dictionary (I believe this is their reference)?
I had an 'o' in 14a too so that one will need revised. I wasn't aware that the 'i' version meant youngster so I did learn something!
The use of degree in 8d is baffling me. I've never seen it used in that way before and still don't know how it works. Is it used in this manner elsewhere in the world or is this taking liberties? I'm not sure if I'm letting my annoyance at the puzzle cloud my judgement on that one!
