Madame is the way to address a French woman, as in Madame Curie. It's officially for married women, like Mrs. in English, but it's often used for any exotic woman, married and French or not.

Madam (or, in French, madame) is a polite form of address for women, often contracted to ma'am. The abbreviation is "Mme" or "Mme" and the plural is mesdames (abbreviated "Mmes" or "Mmes"). The term was borrowed from the French madame (French pronunciation: ​[maˈdam]), which means "my lady".

The general French word for the house is la maison.
