People like me cause inns to be smashed up (9)
I believe the answer is:
nuisances
'people like me cause inns to be smashed up' is the definition.
I can't tell whether this defines the answer.
'cause inns to be smashed up' is the wordplay.
'to be smashed up' indicates anagramming the letters.
'cause'+'inns'='causeinns'
'causeinns' with letters rearranged gives 'NUISANCES'.
(Other definitions for nuisances that I've seen before include "Pests or irritations" , "Annoyances, pains in the neck" , "problems" .)
