Discover Shakespeare's king has a point (5)
I believe the answer is:
learn
'discover' is the definition.
(I know that discover is a more specific form of discover)
'shakespeare's king has a point' is the wordplay.
'shakespeare's king' becomes 'lear' (I've seen this in another clue).
'has' says to put letters next to each other.
'a point' becomes 'n' (North).
'lear'+'n'='LEARN'
(Other definitions for learn that I've seen before include "Ascertain" , "Take in" , "Succeed in school" , "Gain knowledge or skills" , "Acquire 28 across" .)
