An example of the way to stand (8)
I believe the answer is:
instance
'an example' is the definition.
(I know that example can be written as instance)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for instance that I've seen before include "Cite as an example" , "'Example, illustration (8)'" , "Exemplify" , "Case or example from ancients" , "An insect (anag.)" .)
