Modernised Dover - neat arrangement (9)
I believe the answer is:
renovated
'modernised dover neat arrangement' is the definition.
I can't judge whether this definition defines the answer.
'dover neat arrangement' is the wordplay.
'arrangement' indicates anagramming the letters.
'dover'+'neat'='doverneat'
'doverneat' is an anagram of 'RENOVATED'.
Can you help me to learn more?
(Other definitions for renovated that I've seen before include "Healthy again" , "Done up" .)
