Pal, say, about to move (5)
I believe the answer is:
budge
'to move' is the definition.
(to budge is to move slightly)
'pal say about' is the wordplay.
'pal' becomes 'bud' (I've seen this in another clue).
'say' becomes 'eg' (both can mean for example).
'about' shows that the letters should be reversed in order.
'eg' in reverse letter order is 'ge'.
'bud'+'ge'='BUDGE'
(Other definitions for budge that I've seen before include "Make a slight movement" , "Move slightly, or cause shift in opinion" , "Change an opinion" , "Shift or yield" , "Move, stir" .)
