Caught with some maggots (3)
I believe the answer is:
got
'caught' is the definition.
('get' can be a synonym of 'catch')
'with some maggots' is the wordplay.
'with' indicates a hidden word.
'GOT' is hidden within 'some maggots'.
(Other definitions for got that I've seen before include "Acquired" , "Obtained" , "Caught" , "Landed" , "Received; understood" .)
