Some scribe returning cap (5)
I believe the answer is:
beret
'cap' is the definition.
(I know that beret is a type of cap)
'some scribe returning' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'BERET' is hidden within 'scribe returning'.
(Other definitions for beret that I've seen before include "Cap with no brim" , "felt on one's head" , "Kind of floppy cap with no peak" , "Basque headgear" , "item of headwear" .)
