gloucestershire

'region' is the definition.
Both the definition and answer are singular nouns.
Maybe there's an association between them I don't understand?

'excited girls tour cheese' is the wordplay.
'excited' indicates an anagram.
'girls'+'tour'+'cheese'='girlstourcheese'
'girlstourcheese' anagrammed gives 'GLOUCESTERSHIRE'.

Can you help me to learn more?
