Madam

Madam, or madame ( or ), is a polite and formal form of address for women in the English language, often contracted to ma'am (pronounced in American English and this way but also in British English). The term derives from the French madame, from "ma dame" meaning "my lady". In French, the abbreviation is "M" or "Mme" and the plural is mesdames (abbreviated "M" or "Mmes"). These terms ultimately derive from the Latin domina, meaning "mistress".
