Because of the wild animal, don't (7)
I believe the answer is:
forbear
'don't' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'because of the wild animal' is the wordplay.
'because of' becomes 'for' ('for' can mean 'because').
'the wild animal' becomes 'bear' (bears are wild animals).
'for'+'bear'='FORBEAR'
Can you help me to learn more?
(Other definitions for forbear that I've seen before include "Hold back" , "Be patient" , "Refrain from doing something" , "Abstain" .)
