Ideal place for the work of Sir Thomas More (6)
I believe the answer is:
utopia
I believe this clue is a double definition.
'ideal place' is the first definition.
(I've seen this before)
'work of sir thomas more' is the second definition.
(I know that Utopia author Thomas More)
'for the' acts as a link.
(Other definitions for utopia that I've seen before include "Thomas More's favourite place" , "Imaginary place where everything is perfect" , "More's imaginary state" , "Imaginary ideal place" , "Thomas More's ideal state" .)
