Eccentric, however you look at it (4)

I believe the answer is:

kook

I believe this is a double definition.

'eccentric' is the first definition.
(I know that kook is a type of eccentric)

'however you look at it' is the second definition.

(Other definitions for kook that I've seen before include "Crazy" , "US weirdo" , "Palindrome for eccentric person - in America" , "Eccentric person (sl.)" .)

I've seen this clue in The Guardian.
