Regal beverage? (5)
I believe the answer is:
lager
'beverage?' is the definition.
(lager is a kind of beverage)
'regal' is the wordplay.
'regal' anagrams to 'LAGER'.
Though, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for lager that I've seen before include "The drink could be regal" , "A regal sort of drink" , "Light beer needed" , "Lout's drink?" , "Continental beer" .)
