Roof missing from club, say (5)
I believe the answer is:
utter
'say' is the definition.
(to utter something is to say or speak it)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for utter that I've seen before include "Downright" , "Dead" , "Make sounds (but not necessarily words)" , "Total < state" , "Speak, articulate" .)
