mitre

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

'one of those worn by bishop' is the definition.
I can't judge whether this defines the answer.

'trim off goatee finally' is the wordplay.
'off' is an anagram indicator.
'finally' suggests the final letters.
The last letter of 'goatee' is 'e'.
'trim' with letters rearranged gives 'mitr'.
'mitr'+'e'='MITRE'

Can you help me to learn more?

(Other definitions for mitre that I've seen before include "Episcopal headdress" , "symbol of ecclesiastical authority" , "Item of headgear" , "Bishop's headgear - joint" , "Type of joint - bishop's hat" .)
