Rent in Tripoli (3)
I believe the answer is:
rip
'rent' is the definition.
(rent can mean a tear in something)
'in tripoli' is the wordplay.
'in' says the answer is hidden in the clue.
'RIP' can be found hidden inside 'tripoli'.
(Other definitions for rip that I've seen before include "inscription on tomb" , "Letters on a grave stone" , "Letters often seen on gravestones" , "Louche character" , "Tear or split open" .)
