Fuss as ankle-biter swapped ends (6)
I believe the answer is:
racket
'fuss' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for racket that I've seen before include "fiddle" , "Illegal scheme" , "A lot of noise or stringed bat" , "produced at Wimbledon" , "Loud and disturbing noise" .)
