King Edward the humorist (4)

I believe the answer is:

lear

I believe this is a double definition.

'king' is the first definition.
(King Lear)

'edward the humorist' is the second definition.
(nonsense poet Edward Lear, 1812-1888)

(Other definitions for lear that I've seen before include "Mad king" , "troubled king" , "hardly the 7 [NO NONSENSE] type!" , "Lesson" , "The Bard's foolish king" .)

I've seen this clue in The Guardian.
