Villain gets very loud in a ruin, sadly (7)
I believe the answer is:
ruffian
'villain' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'very loud in a ruin sadly' is the wordplay.
'very loud' becomes 'ff' (musical abbreviation).
'in' is an insertion indicator.
'sadly' indicates an anagram.
'a'+'ruin'='aruin'
'aruin' is an anagram of 'ruian'.
'ff' inserted into 'ruian' is 'RUFFIAN'.
'gets' is the link.
Can you help me to learn more?
(Other definitions for ruffian that I've seen before include "Roughneck" , "Lout" , "Violent criminal" , "Aggressive, rude troublemaker" , "Thug" .)
