____ generis: of its own type (3)
I believe the answer is:
sui
'type' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I can't see?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sui that I've seen before include "Legal professional" , "- Generis means unique" .)
