Snare catches male vagabond (5)
I believe the answer is:
tramp
'vagabond' is the definition.
(thesaurus)
'snare catches male' is the wordplay.
'snare' becomes 'trap' ('trap' can be a synonym of 'snare').
'catches' is an insertion indicator.
'male' becomes 'm' (common abbreviation).
'trap' placed around 'm' is 'TRAMP'.
(Other definitions for tramp that I've seen before include "Traveller" , "March heavily like hobo" , "Take a walk" , "man down on his luck" , "Tread heavily (on)" .)
