Regal request? (6)
I believe the answer is:
asking
This might be a double definition.
'regal' is the first definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'request?' is the second definition.

(Other definitions for asking that I've seen before include "Enquiring" , "Begging" , "Appealing" , "Making enquiries" , "It demands explanation!" .)
