It is taken by dancers and speakers (5)
I believe the answer is:
floor
'it is taken by dancers and speakers' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for floor that I've seen before include "Knock down - planking" , "Storey of a building" , "Defeat" , "Base of room - storey" , "Building's base" .)
