Like perfect showjumping round — that’s evident (5)
I believe the answer is:
clear
This might be a double definition.
'like perfect showjumping round' is the first definition.
'clear' can be an answer for 'round' (thesaurus). I am not sure about the 'like perfect showjumping' bit.
'evident' is the second definition.
('clear' can be a synonym of 'evident')
'that's' is the link.
Can you help me to learn more?
(Other definitions for clear that I've seen before include "Plainly" , "Lucid, transparent" , "Easily understood" , "Unimpeded" , "Fine" .)
