Move, stir (5)
I believe the answer is:
budge
I believe this clue is a double definition.
'move' is the first definition.
(to budge is to move slightly)
'stir' is the second definition.
(I know that stir can be written as budge)
(Other definitions for budge that I've seen before include "Cause to alter an opinion or stance, shift" , "Make a slight movement" , "Shift or yield" , "Cornish resort" , "Make the slightest movement" .)
