Affectations evident in the adjustment of the pope’s fire (9)

I believe the answer is:

fopperies

I'm a little stuck... Click here to teach me more about this clue!

'affectations' is the definition.
Both the definition and answer are plural nouns.
Perhaps you can see a link between them that I can't see?

'the adjustment of the pope's fire' is the wordplay.
'the adjustment of' indicates an anagram (I've seen this in other clues).
'popes'+'fire'='popesfire'
'popesfire' is an anagram of 'FOPPERIES'.

'evident in' acts as a link.

Can you help me to learn more?

I've seen this clue in The Hindu.
