Rubbish from Wrotham? (3)
I believe the answer is:
rot
'rubbish' is the definition.
(both can mean nonsense)
'from wrotham?' is the wordplay.
'from' indicates a hidden word.
'ROT' can be found hidden inside 'wrotham'.
(Other definitions for rot that I've seen before include "Break down, waste away" , "Decay - nonsense" , "Decay, perish" , "Corruption" , "Decay in grotesque way" .)
