Composer gets engaged in gorge (7)
I believe the answer is:
satiate
'gorge' is the definition.
(I know that gorge can be written as satiate)
'composer gets engaged' is the wordplay.
'composer' becomes 'satie' (French composer Erik Satie).
'gets' indicates putting letters inside (gets can mean captures or absorbs).
'engaged' becomes 'at' (I've seen this in other clues).
'satie' enclosing 'at' is 'SATIATE'.
'in' is the link.
(Other definitions for satiate that I've seen before include "Completely satisfy" , "Overfill - gorge" , "Gratify fully" , "Have more than enough" , "Fill to satisfaction" .)
