Fine isn't collected by deputy on vacation (6)
I believe the answer is:
dainty
'fine' is the definition.
(I've seen this before)
'isn't collected by deputy on vacation' is the wordplay.
'isn't' becomes 'aint' (I've seen this before).
'collected by' indicates putting letters inside.
'on vacation' says to hollow out the word (remove centre letters).
'deputy' with its middle taken out is 'dy'.
'aint' placed into 'dy' is 'DAINTY'.
(Other definitions for dainty that I've seen before include "Delicately small and pretty" , "Delicate, tasteful" , "Delicate and petite" , "Titbit, delicacy" , "Delicate, neat" .)
