Broken right inside, having popped (5)
I believe the answer is:
burst
'popped' is the definition.
(I've seen this in another clue)
'broken right inside' is the wordplay.
'broken' becomes 'bust' (bust can mean broken).
'right' becomes 'r' (common abbreviation).
'inside' means one lot of letters goes inside another.
'bust' going around 'r' is 'BURST'.
'having' is the link.
(Other definitions for burst that I've seen before include "Pop" , "Blowout" , "Ruptured" , "Suddenly break open" , "Rope to catch cattle" .)
