Contract snag? (5)
I believe the answer is:
catch
This clue is a double definition.
'contract' is the first definition.
(thesaurus)
'snag?' is the second definition.
(snagging is a kind of catching)
(Other definitions for catch that I've seen before include "Apprehend - funny song" , "Arrest" , "Get a grip on" , "potential partner?" , "Good match" .)
