Sample of Zeno's paradoxes in practice in Ring (4)
I believe the answer is:
spar
'practice in ring' is the definition.
'spar' can be an answer for 'ring' (thesaurus). I am not sure about the 'practice in' bit.
'sample of zeno's paradoxes in' is the wordplay.
'sample of' indicates a hidden word (I've seen this in other clues).
'SPAR' can be found hidden inside 'zenos paradoxes in'.
Can you help me to learn more?
(Other definitions for spar that I've seen before include "Raps with wooden beam" , "Box - girder" , "Shadow-box" , "Argue" , "Do up (bird for oven)" .)
