Case or particular example (8)
I believe the answer is:
instance
I believe this is a double definition.
'case' is the first definition.
(I know that case can be written as instance)
'particular example' is the second definition.
(I've seen this before)
(Other definitions for instance that I've seen before include "Case in point" , "'Example, illustration (8)'" , "Canniest (anag) - occurrence" , "Example or single occurrence of something" , "Case or example from ancients" .)
