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 definition defines the answer.
'in the attic' is the wordplay.
'in' says the answer is hidden in the clue.
'EAT' is hidden in the letters of '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" .)
