Encloses scribbles (4)
I believe the answer is:
pens
I believe this clue is a double definition.
'encloses' is the first definition.
'scribbles' is the second definition.
(pen can mean to use a pen)
(Other definitions for pens that I've seen before include "Livestock enclosures" , "birds" , "Dashes off" , "Aphorism, thought" , "Literary thought or reflection" .)
