Sustain oneself in theatrical style (3)
I believe the answer is:
eat
'sustain oneself' is the definition.
I can't judge whether this defines the answer.
'in theatrical style' is the wordplay.
'in' indicates the answer is hidden within the clue.
'EAT' can be found hidden inside 'theatrical style'.
Can you help me to learn more?
(Other definitions for eat that I've seen before include "Ingest" , "Bite, chew and swallow" , "Break bread" , "Do cats - bats? Do bats - cats? (Alice in Wonderland)" , "to do etching?" .)
