Puts the screws on dancing shoes (5)
I believe the answer is:
pumps
'dancing shoes' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pumps that I've seen before include "Mechanical devices that move fluid or gas" , "Moves fluid or gas by pressure or suction" , "footwear" , "needed by cyclists" , "Forces liquid to move; light shoes" .)
