Understanding chap (3)

I believe the answer is:

ken

I believe this is a double definition.

'understanding' is the first definition.
(thesaurus)

'chap' is the second definition.

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

I've seen this clue in The Telegraph.
