Dissolute man (4)
I believe the answer is:
rake
'dissolute man' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for rake that I've seen before include "Debauched person found in the garden" , "Implement for a debauched person" , "Garden tool for a dissolute fellow" , "He made progress" , "Dissolute person" .)
