Messrs., Mmes., Mses., Mss.

In the plural, Mr. becomes Messrs. (pronounced MESSers), and Mrs. becomes Mmes. (pronounced mayDAM). For the plural of the abbreviation Ms.,either Mses. or Mss. (both pronounced MIZZes) can be used.

With a long list of names, it is better to use the plural forms of these titles.

• Messrs. Hamilton, Thorne, Bradley and Clarke addressed the gathering.
• The chair introduced Mmes. Thorington, Warner, Black and Sigurdson.
• Mses. Jacobson, Garner, Roberts and McGill founded the company.

However, with two or three names, you should simply repeat the honorific.
