Decide you’ll go to live in (6)
I believe the answer is:
settle
This might be a double definition.
'decide you'll go' is the first definition.
'settle' can be an answer for 'decide' (synonyms). I'm not sure about the 'you'll go' bit.
'live in' is the second definition.
'settle' can be an answer for 'live' (thesaurus). I am not certain of the 'in' bit.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for settle that I've seen before include "Bring to an end, come to terms" , "Come to rest or decide an argument" , "piece of furniture" , "Put down roots or pay debt" , "form" .)
