Veiled legend in grand finale (6)

I believe the answer is:

ending

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

'finale' is the definition.
(I've seen this in another clue)

'veiled legend in grand' is the wordplay.
'ENDING' is hidden in amongst the letters.
But, I'm uncertain how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for ending that I've seen before include "Finishing" , "Finish" , "Closure" , "Termination, conclusion" , "Close - conclusion" .)

I've seen this clue in The Guardian.
