In plain English: A madame is an old-fashioned way to address a woman, often used for someone who runs a business like a salon or brothel.

The word madame entered English directly from the French phrase ma dame, which literally means "my lady." It is a doublet related to both the informal term madam and the Italian title Madonna.
