White queen that is given support (8)
I believe the answer is:
riesling
'white' is the definition.
(type of white wine)
'queen that is given support' is the wordplay.
'queen' becomes 'r' (abbreviation for regina, e.g. in ER ).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'given' means one lot of letters go next to another.
'support' becomes 'sling' (sling is a type of support for member (ie an arm)).
'r'+'ie'+'sling'='RIESLING'
(Other definitions for riesling that I've seen before include "German/Austrian wine" , "Dry white wine (German)" , "Gin riles the wine" , "Aromatic white wine from the Rhine valley" , "Strange wine for Sir Ingle" .)
