I wasn't expecting the "une" with a profession.
Me neither. I'm thinking that because you're modifying the profession with "parisienne", that the indefinite article appears again.
Why is une used here?
Because there is an adjective with the profession
They repeatedly said in previous lessons that le/la and un/une are never used before a profession. What changed and why?
Would femme be accepted in place of dame?
Femme is woman, dame is lady
Is "un/une chef" not possible in this context?
I though un chef was a boss.
Et pourquoi "madame" n'est pas accepté?
Je peux t'expliquer. 'Madame' veut dire "my lady", pas "lady".
