Very nice drink with Her Majesty once (5)
I believe the answer is:
super
'very' is the definition.
(thesaurus)
'nice drink with her majesty once' is the wordplay.
I cannot quite understand how this works, but
'drink' could be 'sup' (to sup is to drink) and 'sup' is located in the answer.
'her majesty' could be 'er' (Elizabeth Regina) and 'er' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for super that I've seen before include "Excellent; policeman" , "Exceptional" , "Jolly good" , "Great; wonderful" , "Terrific, ace" .)
