Give speech from floor at eight (5)
I believe the answer is:
orate
'give speech' is the definition.
(I've seen this before)
'from floor at eight' is the wordplay.
'from' indicates the answer is hidden within the clue.
'ORATE' is hidden in the letters of 'floor at eight'.
(Other definitions for orate that I've seen before include "Erato (anag.)" , "Give a formal address" , "Speak in florid style" , "Speechify" , "make speeches" .)
