Don't quite know how to explain/ask this one without upsetting anyone without the grid but here goes:
10, 27 - ... Paradise lost (8) ???N??T?
Previous answer was ANTBEAR [... one dentally challenged (when it follows, appeal to refrain from the intolerable) formerly classed in ...]
Prior to that the answer was ODONTIC - making O Don't I can't bear - [Concerned with teeth ...]
I also have AARDVARK for 13a - One of 10 27 gives a US university, topped and turned, £1000; ARMADILLO for 14a - One of 10 27, one right out of mind and sick with love.
A bit strange when I don't know 10 27 but there you go!
