Carousel (5-2-5)
I believe the answer is:
merry-go-round
'carousel' is the definition.
(I know that carousel can be written as merry go round)
This is the entire clue.
(Other definitions for merry-go-round that I've seen before include "Carousel" , "Whirligig" , "Fairground ride" , "Fairground attraction" , "Language widely spoken in India" .)
