Harold stopped missing Edward (3)
I believe the answer is:
hal
'harold' is the definition.
(diminutive, as in Hal Prince)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hal that I've seen before include "Harry, in short" , "future Henry V" , "Henry, in short" , "Shakespeare's Prince_with Falstaff" , "Shakespeare's prince" .)
