Lithe cats dancing, running and jumping, etc. (9)
I believe the answer is:
athletics
'running and jumping etc' is the definition.
I can't tell whether this definition defines the answer.
'lithe cats dancing' is the wordplay.
'dancing' indicates anagramming the letters.
'lithe'+'cats'='lithecats'
'lithecats' with letters rearranged gives 'ATHLETICS'.
Can you help me to learn more?
(Other definitions for athletics that I've seen before include "Track and field sport" , "Sports -- cheat list (anag)" , "Lithe acts observed in sporting contests" , "Oldham and Charlton?" , "Lithe acts (anag)" .)
