That kissable Katharina (4)

I believe the answer is:

kate

I'm a little stuck... Click here to teach me more about this clue!

'katharina' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I don't see?

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for kate that I've seen before include "Cole Porter musical 'Kiss Me ....'" , "'Kiss me ___' (show)" , "Katherine (dim.)" , "'Kiss me, ---' (Shrew)" .)

I've seen this clue in the Evening Standard.
