Father's shaking up Sprite (6)
I believe the answer is:
priest
'father's' is the definition.
(I've seen this before)
'up sprite' is the wordplay.
'up' indicates anagramming the letters (letters get chucked up).
'sprite' with letters rearranged gives 'PRIEST'.
'shaking' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for priest that I've seen before include "Clergyman" , "with orders" , "stunner" , "Conductor of religious service" , "Professional woman perhaps" .)
