'commentary' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe you can see a link between them that I can't see?

'about a bishop's state' is the wordplay.
'about' indicates putting letters inside.
'bishop' becomes 'rr' (abbreviation for Right Reverend).
'state' becomes 'nation' (synonyms).
'a'+'rr'='arr'
'arr' inserted inside 'nation' is 'NARRATION'.
