Pop West gives a hand (3)
I believe the answer is:
paw
'a hand' is the definition.
(I know that hand can be written as paw)
'pop west' is the wordplay.
'pop' becomes 'pa' (both can mean father).
'west' becomes 'W' (abbreviation).
'pa'+'w'='PAW'
'gives' acts as a link.
(Other definitions for paw that I've seen before include "Animal's foot" , "Manhandle" , "Cat's foot" , "Hand; foot" , "Eg, a dog's foot" .)
