Hang about during telling error (6)
I believe the answer is:
linger
'hang about' is the definition.
(I've seen this before)
'during telling error' is the wordplay.
'during' indicates the answer is hidden within the clue.
'LINGER' can be found hidden inside 'telling error'.
(Other definitions for linger that I've seen before include "Dally, stay on" , "Hang back awhile" , "Stay on as if reluctant to leave" , "Remain for long" , "Be slow to leave" .)
