Girl holds to a man (5)
I believe the answer is:
anton
'a man' is the definition.
(I've seen this before)
'girl holds to' is the wordplay.
'girl' becomes 'ann'.
'holds' is an insertion indicator.
'ann' placed around 'to' is 'ANTON'.
(Other definitions for anton that I've seen before include "-- Chekhov, Russian dramatist" , "Boy" , "..... Chekov" , "Chekhov, say" , "Chekhov maybe" .)
