Crook's party has chunky chips on the side with everything served up (6)
I believe the answer is:
staffs
'chunky chips on the side with everything served up' is the definition.
I can't judge whether this definition defines the answer.
'crook's party' is the wordplay.
'crook' becomes 'staff' (I've seen this before).
'party' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'staff'+'s'='STAFFS'
'has' is the link.
Can you help me to learn more?
(Other definitions for staffs that I've seen before include "Where Tamworth is" , "sticks" , "Weapons; county (abbr.)" , "Cannock's county (abbrev.)" , "Nineteenth century artist" .)
