what's the difference between miss and ma'am
Miss "Miss" is the proper form for addressing all young ladies. It is sometimes used when addressing a younger adult woman, for example, "May I help you, Miss?" In the United States, the titles of "Ma'am" or "Madam" are sometimes used instead of "Miss." Use of any of these terms implies marital status.[dubious â€“ discuss] Some take offense to the use of "Ma'am" or "Madam" because it indicates that the speaker thinks the woman being addressed must certainly be married due to her apparent age, and some take offense to the use of the terms "Ma'am" or "Madam" because of their association with houses of ill repute. On the other hand, addressing a woman as "Miss" may be taken as patronizing.
Mrs. Mrs. (American English) or Mrs (British English) (Standard English pronunciation /ˈmɪsɪz/) is a commonly used English honorific used for women, usually for those who are married and who do not instead use another title (or rank), such as Dr, Professor, President, Dame, Prime Minister, etc. In most Commonwealth countries, a full stop (period) is usually not used with the title. In the United States and Canada a period is usually used (see Abbreviation).[1]
