Draw in art, possibly (5)
I believe the answer is:
train
'draw' is the definition.
(I know that train is a more specific form of the action drag)
'in art possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'in'+'art'='inart'
'inart' is an anagram of 'TRAIN'.
(Other definitions for train that I've seen before include "Form of transport" , "School - transport" , "Point" , "become physically fit" , "Teach, series (of events)" .)
