Accept the defect, say, and start dancing (4,3,5)
I believe the answer is:
take the floor
'start dancing' is the definition.
(I've seen this before)
'accept the defect say' is the wordplay.
'accept' becomes 'take' (to accept is to take possession of).
'defect say' becomes 'floor' (I can't justify this - if you can you should believe this answer much more).
'take'+'the'+'floor'='TAKE THE FLOOR'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for take the floor that I've seen before include "Rise to speak" , "Start dancing" , "Stand up to dance or to make a speech" , "Start to dance" , "Rise to address a meeting" .)
