Give speech from floor at eleven (5)
I believe the answer is:
orate
'give speech' is the definition.
(I've seen this before)
'from floor at eleven' is the wordplay.
'from' says the answer is hidden in the clue.
'ORATE' is hidden within 'floor at eleven'.
(Other definitions for orate that I've seen before include "Deliver a speech" , "Pontificate" , "Make a lengthy speech" , "Give speech" , "Speak publicly" .)
