Moving lout is no answer (8)
I believe the answer is:
solution
'answer' is the definition.
(I know that answer can be written as solution)
'moving lout is no' is the wordplay.
'moving' indicates an anagram (letters are moved around).
'lout'+'is'+'no'='loutisno'
'loutisno' is an anagram of 'SOLUTION'.
(Other definitions for solution that I've seen before include "13 across" , "Holmes often sought?" , "Liquid mixture of two or more substances" , "Puzzle's answer" , "What you want here" .)
