Knight in boozer with single noblewoman in Paris (7)
I believe the answer is:
baronne
'noblewoman in paris' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'knight in boozer with single' is the wordplay.
'knight' becomes 'N' (chess abbreviation).
'in' indicates putting letters inside.
'boozer' becomes 'bar'.
'with' says to put letters next to each other.
'single' becomes 'one' (a single thing - only one).
'bar'+'one'='barone'
'n' going within 'barone' is 'BARONNE'.
Can you help me to learn more?
(Another definition for baronne that I've seen is " French aristo".)
