Boozers regularly disposed of winnings (4)
I believe the answer is:
inns
'boozers' is the definition.
'regularly disposed of winnings' is the wordplay.
'regularly disposed of' means one should take alternating letters.
The alternate letters of 'winnings' are 'INNS'.
(Other definitions for inns that I've seen before include "Old-time hostelries" , "King's ..., for the legal eagles" , "travellers' accommodation" , "Drink here and learn about the King's law" , "Old hostelries or pubs" .)
