Discharge from bench (6)
I believe the answer is:
settle
This clue is a double definition.
'discharge' is the first definition.
(thesaurus)
'bench' is the second definition.
(I know that settle is a type of bench)
'from' is the link.
(Other definitions for settle that I've seen before include "rest > put in order" , "Decide - colonise" , "Become established, make one's home" , "Bring to an end, come to terms" , "Make home, put down roots" .)
