Glare wildly (like King Lear?) (5)
I believe the answer is:
regal
'king lear?' is the definition.
The answer and definition are not the same part of speech.
'glare wildly' is the wordplay.
'wildly' indicates anagramming the letters.
'glare' anagrammed gives 'REGAL'.
'like' is the link.
Can you help me to learn more?
(Other definitions for regal that I've seen before include "King-like" , "Kingly glare?" , "Portable organ" , "Magnificent, dignified" , "Showing great dignity" .)
