Doctor and I outside a house — in some state? (7)
I believe the answer is:
idahoan
'in some state?' is the definition.
(Idahoan means relating to Idaho)
'doctor and i outside a house' is the wordplay.
'doctor' indicates anagramming the letters.
'outside' means one lot of letters goes inside another.
'a house' becomes 'hoa' (I am not sure about this - if you are sure you should believe this answer much more).
'and'+'i'='andi'
'andi' with letters rearranged gives 'idan'.
'idan' enclosing 'hoa' is 'IDAHOAN'.
Can you help me to learn more?
(Other definitions for idahoan that I've seen before include "Citizen of Boise, perhaps" , "from Boise, say" , "from a certain state" , "man in a state?" .)
