Somehow detest being checked (6)
I believe the answer is:
tested
'being checked' is the definition.
(I've seen this in another clue)
'somehow detest' is the wordplay.
'somehow' indicates anagramming the letters.
'detest' anagrammed gives 'TESTED'.
(Other definitions for tested that I've seen before include "Subjected to examination or trial" , "Tried or examined" , "Put to the proof" , "Measured for quality or reliability" , "Proved" .)
