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 a hidden word.
'LINGER' is hidden within '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" .)
