How would you use the word Ms in addressing more than one woman?

Answer 1

There is no plural, because "Ms" is a made-up abbreviation invented by feminists who unfortunately did not think through the issue. The correct plural for Miss is Misses; and for Mrs. (which is short for "mistress") is Mesdames, or Mmes., which is the plural of Madame. By the same token, two gentlemen are addressed as Messrs. for Messieurs, plural of Monsieur. So two women would be saluted as Mmes. Jones and Smith. Otherwise, you'll Ms the boat.

Another answer:

The above suggests that there are some abbreviations that were not 'made up', which is an interesting idea. Where did they come from then, I wonder?

All three forms of address commonly used for women (Miss, Mrs, and Ms) derive from the word 'mistress'. Traditionally, 'Miss' is used for an unmarried woman and 'Mrs' for a married woman. Many women do not see why they should have to proclaim their marital status to the world when men do not have to do so, so they have adopted the form Ms to remove that distinction. This does not make them feminists (not that there is anything wrong with being such), nor have they failed to 'think through the issue'. There is no 'issue'.

If you wish to write to two women who use the form Ms, write 'Dear Ms Smith and Ms Jones'. If you wish to refer to them in speaking, refer to them as 'Ms Smith and Ms Jones'. Certainly there is no plural of Ms, any more than there is a plural of Mrs (as the previous contributor proved by having to resort to a different language to find one).
