A new rake in motion, stir again (8)
I believe the answer is:
reawaken
'stir again' is the definition.
'a new rake in motion' is the wordplay.
'in motion' indicates anagramming the letters (I've seen this in other clues).
'a'+'new'+'rake'='anewrake'
'anewrake' with letters rearranged gives 'REAWAKEN'.
(Other definitions for reawaken that I've seen before include "Bring to life again" , "spring again" , "Revive" , "Rouse again from sleep" , "Arouse again, interest say" .)
