Like a king (5)
I believe the answer is:
regal
'like a king' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for regal that I've seen before include "Imperial, majestic" , "Royal - 5 down (anag)" , "Kingly glare?" , "fit for the Queen" , "befitting a king" .)
