Goes round giving entertainment (5)
I believe the answer is:
turns
'goes' is the definition.
(turning is a kind of going)
'round giving entertainment' is the wordplay.
'round' becomes 'turn' (synonyms).
'giving entertainment' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'turn'+'s'='TURNS'
Can you help me to learn more?
(Other definitions for turns that I've seen before include "Moves in a new direction" , "Bends" , "Changes direction" , "Rotations" , "Goes off" .)
