Crossword Genius

Examiner of dissipated crones? (6)

Ross

I believe the answer is:

censor

Here is my best explanation:

'examiner' is the definition.

'dissipated crones?' is the wordplay.
'dissipated' indicates anagramming the letters.
'crones' with letters rearranged gives 'CENSOR'.

'of' acts as a link.
