More work from Sir Thomas (6)
I believe the answer is:
utopia
'more work' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for utopia that I've seen before include "Impracticable state of perfection" , "More's ideal world" , "Literally nowhere" , "More's perfect society on an imaginary island" , "Sir Thomas More's perfect place" .)
