Giving a ruling about two gin cocktails (8)
I believe the answer is:
reigning
'giving a ruling about two gin cocktails' is the definition.
The definition and answer can be both to do with social activities as well as being present participle verbs.
Maybe you can see a link between them that I can't see?
'ruling about two gin cocktails' is the wordplay.
'ruling' becomes 'reining' ('rein' can be a synonym of 'rule').
'about' indicates putting letters inside.
'two gin cocktails' becomes 'g' (I can't justify this - if you can you should believe this answer much more).
'reining' enclosing 'g' is 'REIGNING'.
Can you help me to learn more?
(Another definition for reigning that I've seen is " Ruling over like a sovereign".)
