Vision certainly embodied by rowing crew (8)
I believe the answer is:
eyesight
'vision' is the definition.
(eyesight is your vision)
'certainly embodied by rowing crew' is the wordplay.
I cannot really understand how this works, but
'certainly' could be 'yes' (both can be used to answer in the affirmative) and 'yes' is present in the answer.
'crew' could be 'eight' (an eight-person rowing team) and 'eight' is found in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for eyesight that I've seen before include "Visual faculty" , "Requirement to look" , "Yes, eight required for vision" , "Perceptive faculty" , "Ability to see" .)
