Kingly hero Yale discovered in their midst (5)
I believe the answer is:
royal
'their midst' is the definition.
I can't judge whether this defines the answer.
'kingly hero yale discovered' is the wordplay.
'discovered' indicates the answer is hidden within the clue (remove the letters covering the answer in the clue).
'ROYAL' can be found hidden inside 'kingly hero yale'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for royal that I've seen before include "Wills, perhaps" , "- - Shakespeare Company (RSC)" , "like The Grand Old Duke of York, perhaps" , "First-rate" , "Old gold coin -- stag with 12 or more points" .)
