State of an upper-class bad-hat? (4)
I believe the answer is:
utah
'state' is the definition.
(Utah is a US state)
'an upper-class bad-hat?' is the wordplay.
'an upper class' becomes 'u' (as in U- and non-U speech).
'bad' indicates an anagram.
'hat' anagrammed gives 'tah'.
'u'+'tah'='UTAH'
'of' acts as a link.
(Other definitions for utah that I've seen before include "Mormon US state" , "US state, capital Salt Lake City" , "American state associated with Mormons and their faith" , "Great Salt Lake state" , "member of union" .)
