utopia

I'm a little stuck... Click here to teach me more about this clue!

'more work' is the definition.
(work by Sir Thomas More)

I don't understand how the remainder of the clue works.

(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" .)

I've seen this clue in the Evening Standard.
