Pluck β intestines (4)
I believe the answer is:
guts
I believe this is a double definition.
'pluck' is the first definition.
(I've seen this in another clue)
'intestines' is the second definition.
(I know this)
(Other definitions for guts that I've seen before include "Belly; courage" , "Eat greedily" , "Inside - bottle!" , "Daring" , "Fortitude - innards" .)
