State it's genteel to raise one's hat (4)
I believe the answer is:
utah
'state' is the definition.
(Utah is a US state)
'genteel to raise one's hat' is the wordplay.
I cannot really understand how this works, but
an anagram of 'hat' is 'tah' which is located in the answer.
A single letter 'u' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'it's' is the link.
Can you help me to learn more?
(Other definitions for utah that I've seen before include "State of the union" , "The American Morman state" , "US state settled by the Mormons" , "State of Western USA" , "Brigham Young state" .)
