Option to change someone who lives in a place (11)
I believe the answer is:
alternative
'option' is the definition.
(synonyms)
'change someone who lives in a place' is the wordplay.
I cannot really understand how this works, but
'change' could be 'alter' (synonyms) and 'alter' is located in the answer.
'someone' could be 'native' (native is a kind of someone) and 'native' is found in the answer.
No letters remain.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for alternative that I've seen before include "(Of two things) mutually exclusive" , "One of two or more available possibilities" , "One possible option" , "Substitute" , "One of a number of possibilities" .)
