Well done Ginge, cheers thea.
aristo - Sorry I didn't get time to explain. I was in a rush today and had to vote and go somewhere knowing I wouldn't be back until post 10pm.
You have the parse almost wrapped up. Here goes with my explanation.
With = w + seconds = Mo Mo
to spare = [p1494 of Chambers 12 Edition - 2nd Def - opening or slit in a skirt or trousers (Scots)} I have taken it as 'an opening' - For RCSA - Roman Catholics answer
Then all of it is BACK
Thus - oM (ASCR) oM w
in = container
time = T + He'll
= T (H [oM { ASCR } oM w] e'll)
H'ell - is indeed the &lit part running into the rest being the extended DEF (which I feel was certainly needed)
I did look at 'Spare' Definition 1 - 'To allow oneself' but thought this may have been a stretch to just mean 'allow
So I used two containers - Spare & in - which maybe misdirected too much
Thoughts?
