Have second thoughts about hypocrisy (6)

I believe the answer is:

recant

I'm a little stuck... Click here to teach me more about this clue!

'have second thoughts about hypocrisy' is the definition.
I can't tell whether this defines the answer.

'about hypocrisy' is the wordplay.
'about' becomes 're' (regarding).
'hypocrisy' becomes 'cant' (I've seen this in other clues).
're'+'cant'='RECANT'

Can you help me to learn more?

(Other definitions for recant that I've seen before include "Renounce (a heretical belief)" , "Revoke a former declaration" , "Formally reject a former belief" , "Retract opinion" , "Withdraw a former declaration" .)

I've seen this clue in The Guardian, The Globe and Mail and The Irish News.
