Rustic tramp nearly gets abdominal pain (7)
I believe the answer is:
bucolic
'rustic' is the definition.
(I know that bucolic is a type of rustic)
'tramp nearly gets abdominal pain' is the wordplay.
'tramp' becomes 'bum' (both can mean a homeless person).
'nearly' means to remove the last letter.
'gets' is a charade indicator (letters next to each other).
'abdominal pain' becomes 'colic' (I've seen this before).
'bum' with its last letter taken off is 'bu'.
'bu'+'colic'='BUCOLIC'
(Other definitions for bucolic that I've seen before include "Characteristic of country life" , "Pastoral poem" , "Rustic - pastoral" , "Relating to rural life" , "Of rural or pastoral life" .)
