People will be annoyed to be given it (7)
I believe the answer is:
offence
'it' is the definition.
The definition suggests a singular noun which matches the answer.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for offence that I've seen before include "Hurting of feelings" , "The action of attacking an enemy" , "Misdeed" , "Displeasure" , "An act punishable by law" .)
