Mademoiselle is a French noun meaning “Miss,” used as a formal form of address for an unmarried woman. In French-speaking contexts it functions as the feminine equivalent of Monsieur and corresponds to mademoiselle in traditional etiquette. In English-language texts it is often used humorously or in borrowing as a proper noun or stylistic term. Pronunciation requires careful French vowel and nasal consonant treatment and final syllable reduction in many non-French contexts.
