"ken", iirc, is Scottish for "knowledge [of]", experience, perception, etc.

Last time I heard it use in popular media was by Sheldon on The Big Bang Theory.

I looked it up eons ago when I read James Clavell's historical novel about the founding of Hong Kong. Lots of Scottish phrases...And Cantonese. "Dew neh low..."
