Dilapidated sideboards getting batterings (10)
I believe the answer is:
broadsides
'batterings' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'dilapidated sideboards' is the wordplay.
'dilapidated' indicates anagramming the letters.
'sideboards' is an anagram of 'BROADSIDES'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for broadsides that I've seen before include "Verbal attacks" , "Strongly critical attacks" .)
