Supervise some of the riotin' spectators (7)
I believe the answer is:
inspect
'supervise' is the definition.
The definition and answer can be both to do with perception as well as being verbs in their base form.
Perhaps you can see an association between them that I don't see?
'some of the riotin' spectators' is the wordplay.
'some of' indicates the answer is hidden within the clue.
'INSPECT' is hidden in the letters of 'riotin spectators'.
Can you help me to learn more?
(Other definitions for inspect that I've seen before include "Carefully examine" , "Ecamine closely" , "Assess; examine" , "Go over" , "test" .)
