Kip used to pass the hat around at financial centre (6)
I believe the answer is:
catnap
'kip' is the definition.
(I know that catnap has the is a more specific form of the action kip)
'hat around at financial centre' is the wordplay.
'hat' becomes 'cap' (cap is a type of hat).
'around' indicates putting letters inside.
'centre' says to take the centre.
The middle letter of 'financial' is 'n'.
'at'+'n'='atn'
'cap' enclosing 'atn' is 'CATNAP'.
'used to pass the' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for catnap that I've seen before include "Drop off" , "(Tom's) snooze?" , "Brief time out" , "Kip" , "Short sleep" .)
