Frank has the ability and got things done (6)
I believe the answer is:
candid
'frank' is the definition.
(I know that frank can be written as candid)
'the ability and got things done' is the wordplay.
I cannot really understand how this works, but
'ability' could be 'id' (id is a kind of ability) and 'id' is present in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
The remaining letters 'cad' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'has' acts as a link.
Can you help me to learn more?
(Other definitions for candid that I've seen before include "Very clear" , "Frank, honest" , "Free and frank" , "Frank - unbiased" , "Forthrightly sincere" .)
