Almost everyone knows the meaning of "Mr.", "Mrs.", and "Miss". "Mr." is used before the names of gentlemen. "Mrs." is for married women and "Miss" is for single women. But what is "Ms."?

For some time, businessmen in the US have used "Ms." before a woman's name when they do not know whether or not the woman is marrieD.Today, however, many women prefer to use "Ms." rather than "Mrs." or "Miss". The word "Mr." does not tell us whether a man is married or not. Many women think this is an advantage for men. They want to be equal to men in this way. These women feel that it is not important for people to know whether or not they are marrieD.

There are some problems with "Ms.", however. Not all women like it. Some like the older ways of doing things. Some find it difficult to pronounce. ("Ms." sounds like [miz].) Generally, young women like it better than older women do. It is difficult to know whether "Ms." will be used by more American women in the future or not. What do you think of this change?
