Mean to get treatment - I am in a state (5)
I believe the answer is:
maine
'a state' is the definition.
(US state)
'mean to get treatment i am' is the wordplay.
'mean' becomes 'ne' (I can't explain this - if you can you should believe this answer much more).
'to get' says to put letters next to each other.
'treatment' is an anagram indicator (letters treated or processed differently).
'i'+'am'='iam'
'iam' is an anagram of 'mai'.
'ne' after 'mai' is 'MAINE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for maine that I've seen before include "North-easterly US state" , "US state, capital Augusta (5)" , "Part of America" , "state of USA" , "somewhere in America" .)
