can a married woman be addressed as ms
``Ms'' or ``Ms.'' (normally /ˈmɪz/, but also /məz/, or /məs/ when unstressed) is an English honorific used with the last name or full name of a woman, intended as a default form of address for women regardless of their marital status. Like ``Miss'' and ``Mrs.'', the term ``Ms.'' has its origins in the female English title once used for all women, ``Mistress''. It has its origin in the 17th century and was revived into mainstream usage in the 20th century. In the UK and the majority of 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).
