Grant an unprecedented amount! (4)

I believe the answer is:

cede

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

'grant' is the definition.
(I know that grant can be written as cede)

'an unprecedented amount' is the wordplay.
'CEDE' is hidden within the letters.
But, I am uncertain how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for cede that I've seen before include "Surrender or yield" , "21 across" , "Allow" , "Transfer" , "Give up (eg, power)" .)

I've seen this clue in the Evening Standard.
