Drink left over in group refreshed army (6,4)
I believe the answer is:
bloody mary
'drink' is the definition.
(Bloody Mary is an example)
'left over in group refreshed army' is the wordplay.
'left over' becomes 'lo' (this could be a standard abbreviation I've not previously seen).
'in' means one lot of letters goes inside another.
'group' becomes 'body' (body can mean an organisation or group).
'refreshed' indicates anagramming the letters.
'army' is an anagram of 'mary'.
'body'+'mary'='bodymary'
'lo' inserted inside 'bodymary' is 'BLOODY MARY'.
Can you help me to learn more?
(Other definitions for bloody mary that I've seen before include "killing Queen?" , "Vodka-based cocktail" , "The Red Queen" , "something to drink" , "Tomato juice and vodka" .)
