Do what's necessary in the attic (3)
I believe the answer is:
eat
'do what's necessary' is the definition.
I can't tell whether this defines the answer.
'in the attic' is the wordplay.
'in' indicates a hidden word.
'EAT' is hidden within 'the attic'.
Can you help me to learn more?
(Other definitions for eat that I've seen before include "Break bread" , "Consume for tea" , "Partake of" , "Bit, chew and swallow" , "Use a knife and fork" .)
