US city in Maine chaotic without a hospital (7)
I believe the answer is:
anaheim
'us city' is the definition.
'anaheim' can be an answer for 'city' (I have seen 'Californian city' mean 'anaheim' so perhaps 'city' could also mean 'anaheim'). I am not certain of the 'us' bit.
'maine chaotic without a hospital' is the wordplay.
'chaotic' indicates an anagram.
'without' means one lot of letters goes inside another ('without' can be similar in meaning to 'outside').
'hospital' becomes 'H' (abbreviation for hospital).
'maine' with letters rearranged gives 'aneim'.
'a'+'h'='ah'
'aneim' placed around 'ah' is 'ANAHEIM'.
'in' is the link.
Can you help me to learn more?
(Other definitions for anaheim that I've seen before include "Californian city" , "Disneyland's home" .)
