ken

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

If this is the answer, I'm afraid I cannot explain it.

(Other definitions for ken that I've seen before include "Notice" , "Understanding - boy's name" , "Awareness" , "Identify; -- Livingstone" , "Know; man's name" .)

I've seen this clue in the Evening Standard.
