Where a new hat goes with the uniform (4)
I believe the answer is:
utah
'where a' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'new hat goes with the uniform' is the wordplay.
'new' indicates an anagram.
'goes with' says to put letters next to each other.
'the uniform' becomes 'u' (phonetic alphabet: alpha, bravo, charlie etc.).
'hat'+'u'='hatu'
'hatu' with letters rearranged gives 'UTAH'.
Can you help me to learn more?
(Other definitions for utah that I've seen before include "The "Beehive" State, capital Salt Lake City" , "Brigham Young state" , "American state, capital Salt Lake City" , "US state N. of Arizona" , "A hut for the Mormons, oddly" .)
