"Shrunk and shrunken"?

[Mehrgan]

Hi,
Can please anyone tell me if these words can always be interchangably used?

Thanks.

To my knowledge, no. Shrunken is an adjective, while shrunk is a past participle. So whenever there's an occasion to use an adjective, use shrunken:
When I last saw her, she looked small, shrunken and pathetic.
I still remember that woman selling shrunken baboon heads.
