Tramps with urge to enter drinking establishments (7)
I believe the answer is:
beggars
'tramps' is the definition.
(both can mean a homeless person)
'urge to enter drinking establishments' is the wordplay.
'urge' becomes 'egg' (I've seen this before).
'to enter' is an insertion indicator.
'drinking establishments' becomes 'bars' (I've seen this before).
'egg' going within 'bars' is 'BEGGARS'.
'with' acts as a link.
(Other definitions for beggars that I've seen before include "Bums" , "'If wishes were horses . . . . . . . would ride'" , "Mendicants" .)
