"What did I say!?" (3)
I believe the answer is:
see
'what did i say?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for see that I've seen before include "District of a bishop - or Pope" , "responsibility of a bishop" , "Bishop's responsibility; observe" , "Up-and-down motion" , "View; realise" .)
