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

'castilian consort' is the definition.
The definition suggests a singular noun which matches the answer.

'is a ringer leader in abbey' is the wordplay.
'ringer' becomes 'bell' (I've seen this before).
'leader in' indicates taking the first letters.
The initial letter of 'abbey' is 'a'.
'is'+'a'+'bell'+'a'='ISABELLA'

Can you help me to learn more?

(Other definitions for isabella that I've seen before include "drab colour" , "Wife of Edward II" , "Ferdinand V's queen" , "Spanish queen who was patroness to Columbus" , "Bails Lea out for the name" .)
