McKinnon of "SNL” (4)
I believe the answer is:
kate
'mckinnon of snl' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for kate that I've seen before include "Katherine (dim.)" , "'Kiss me ___' (show)" , "Cole Porter musical 'Kiss Me ....'" , "'Kiss me, ---' (Shrew)" .)
