Worked out mostly grand, say, like sunlit uplands? (7)
I believe the answer is:
utopian
'worked out mostly grand say like sunlit uplands?' is the definition.
I can't judge whether this definition defines the answer.
'worked out mostly grand say' is the wordplay.
'worked' indicates an anagram.
'mostly' means to remove the last letter (most but not all of the word).
'grand say' becomes 'piano' (grand is a kind of piano).
'piano' with its final letter taken away is 'pian'.
'out' is an anagram of 'uto'.
'uto'+'pian'='UTOPIAN'
Can you help me to learn more?
(Other definitions for utopian that I've seen before include "Really ideal in perfect fictional country" , "More work was literally so" , "Just perfect, as in Thomas More's ideal country" , "Unworkable" , "Just perfect as in Thomas More's fictional country" .)
