Resolve to get a long wooden bench (6)
I believe the answer is:
settle
This clue is a triple definition!
'resolve' is the first definition.
(I know that settle is a kind of resolve)
'to get' is the second definition.
(thesaurus)
'a long wooden bench' is the third definition.
(I've seen this before)
(Other definitions for settle that I've seen before include "Comes to an arrangement with the bench?" , "Make permanent home, stop wandering" , "Put down roots or pay debt" , "Colonise the bench" , "Light upon" .)
