Member in a neat arrangement shows refinement (7)
I believe the answer is:
elegant
'member in a neat arrangement shows refinement' is the definition.
I can't tell whether this defines the answer.
'member in a neat arrangement' is the wordplay.
'member' becomes 'leg' (member can mean a limb).
'in' is an insertion indicator.
'arrangement' is an anagram indicator.
'neat' anagrammed gives 'eant'.
'leg' placed inside 'eant' is 'ELEGANT'.
Can you help me to learn more?
(Other definitions for elegant that I've seen before include "Tasteful and refined in appearance" , "Graceful - refined" , "Neat leg? (anag)" , "Fine" , "Ingenious" .)
