I believe the answer is:

oral

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

'said' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for oral that I've seen before include "Kind of exam" , "Exam using speech" , "Spoken exam" , "Type of exam" , "Type of examination" .)

I've seen this clue in the Evening Standard.
