mademoiselle

Firstly, it's a french term defining a lady who is not married. Now we use it just for a lady.

A French diminuitive of "Madame"; "Mademoiselle" means "My little lady". It once was used to signify an unmarried woman, but concidering that it is a diminutive of "Madame", now it is just used for girls and young women, and the professional title for women is "Madame".

Still, Mademoiselle is used for young women by their admirers.

This French teacher is insane. She is also the epitome of a prude. Will flip out at you for talking in English or not knowing how to conjugate verbs in the subjonctif. Freaking crazy. She throws markers at students' heads and does the Thriller dance at homecoming.
