Our gate damaged causes anger (7)
I believe the answer is:
outrage
'anger' is the definition.
(I know that outrage is a type of anger)
'our gate damaged' is the wordplay.
'damaged' indicates anagramming the letters.
'our'+'gate'='ourgate'
'ourgate' with letters rearranged gives 'OUTRAGE'.
'causes' is the link.
(Other definitions for outrage that I've seen before include "Extreme indignation" , "Violate" , "Incense and offend" , "Shock grossly" , "Gross affront to decency" .)
