A drink date that leads to conflict (9)
I believe the answer is:
agincourt
'a drink date that leads to conflict' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'a drink date' is the wordplay.
'drink' becomes 'gin' (gin is an alcoholic drink).
'date' becomes 'court' (I've seen this in another clue).
'a'+'gin'+'court'='AGINCOURT'
Can you help me to learn more?
(Other definitions for agincourt that I've seen before include "October twenty four, 1415 battle" , "Battleground" , "battle site" , "English victory in 1415" , "where Henry met Constable" .)
