Follows party and General Staff (4)
I believe the answer is:
dogs
'follows' is the definition.
(dog can mean to follow)
'party and general staff' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'and' means one lot of letters go next to another.
'general staff' becomes 'gs' (this could be a standard abbreviation I've not previously seen).
'do'+'gs'='DOGS'
Can you help me to learn more?
(Other definitions for dogs that I've seen before include "Hounds" , "pets" , "Shadows" , "Pursues" , "eg 27 terriers" .)
