Put in order, buy, eat -- lovely! (6)
I believe the answer is:
beauty
'lovely' is the definition.
(thesaurus)
'put in order buy eat' is the wordplay.
'put in order' indicates an anagram (letters put into the right order).
'buy'+'eat'='buyeat'
'buyeat' with letters rearranged gives 'BEAUTY'.
(Other definitions for beauty that I've seen before include "sometimes put before queen?" , "Eye-pleasing quality" , "See 12" , "excellence" , "Aesthetic quality" .)
