A bishop unsettled by dean ultimately offering less latitude (9)

I believe the answer is:

narrowing

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

'less latitude' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'a bishop unsettled by dean ultimately' is the wordplay.
'a bishop' becomes 'rr' (abbreviation for Right Reverend).
'unsettled' becomes 'owing' (I've seen this before).
'by' says to put letters next to each other.
'dean ultimately' becomes 'na' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'rr'+'owing'='rrowing'
'rrowing' after 'na' is 'NARROWING'.

'offering' acts as a link.

Can you help me to learn more?

(Other definitions for narrowing that I've seen before include "Becoming less wide" , "Getting fine" .)
