'province' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I can't see?

'festivity around island' is the wordplay.
'festivity' becomes 'gala' (gala is a kind of festivity).
'around' is a reversal indicator.
'island' becomes 'ait' (term for a small island).
'ait' in reverse letter order is 'tia'.
'gala'+'tia'='GALATIA'
