bridesmaid

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

'role at wedding' is the definition.
I can't judge whether this definition defines the answer.

'bishop is admired performing' is the wordplay.
'bishop' becomes 'b' (abbreviation used in chess).
'performing' indicates an anagram.
'is'+'admired'='isadmired'
'isadmired' with letters rearranged gives 'ridesmaid'.
'b'+'ridesmaid'='BRIDESMAID'

Can you help me to learn more?
