Humorous writer amuses a king to some extent
I believe the answer is:
saki
'humorous writer' is the definition.
'saki' can be an answer for 'writer' (I've seen this before). I am not certain of the 'humorous' bit.
'amuses a king to some extent' is the wordplay.
'to some extent' indicates a hidden word.
'SAKI' is hidden within 'amuses a king'.
Can you help me to learn more?
(Other definitions for saki that I've seen before include "Author H. H. Munro's pseudonym" , "Japanese alcoholic drink made from rice" , "Monkey; author" , "Short-story writer" , "Pen-name of Hector Hugh Munro, d. 1916" .)
