All there in repetitious anecdote (4)
I believe the answer is:
sane
'all there' is the definition.
('not all there' can mean insane)
'in repetitious anecdote' is the wordplay.
'in' says the answer is hidden in the clue.
'SANE' is hidden within 'repetitious anecdote'.
(Other definitions for sane that I've seen before include "Right-minded" , "Not mad" , "Mentally healthy" , "Compos mentis" , "Rational" .)
