Frank has the ability, having performed (6)
I believe the answer is:
candid
'frank' is the definition.
(synonyms)
'the ability having performed' is the wordplay.
'the ability' becomes 'can' (I can't explain this - if you can you should give a lot more credence to this answer).
'having' says to put letters next to each other.
'performed' becomes 'did' ('do' can be a synonym of 'perform').
'can'+'did'='CANDID'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for candid that I've seen before include "'Forthright, open (6)'" , "Truthful, frank" , "Forthrightly sincere" , "Blunt; frank" , "Truthful and straightforward" .)
