I'm beginning to worry that (7) is going to earn me more brickbats than bouquets...it had been clued rather tenuously to avoid its early solution(which would quickly lead to the others with reference to Chambers) - looking at it from right to left may assist.
The clue for 7 didn't help me, but based on the preamble I just checked out the definitions for the answers to 1-6 and something (the answer!) came up.
Peterm- I wasn't sure of the spelling for no 4, but decided it didn't matter (too much).As well as swithering about the 'i' or 'y', I felt there was maybe a surplus 'm'.
(4) is spelt with i rather than y peterm[not very well indicated in retrospect a/one/1(i)]...and (7) is rather tortuous - the ? after legend is certainly called for, it probably needs a ?! after knits also.
