Ms. will have scaled the heights...

Dear teacher,

Please explain these words in the paragraph.

"With the flexible ways to the English language, it probably won’t be too long before “manuscript and milisecond” have to move over to make way for a new dictionary definition. “Ms. will have scaled the heights of grammatical respectability”.

Please explain the underlined sentence.
Thank you very much

It says that the title “Ms.” (which is used instead of Miss or Mrs.) will climb to a level of high acceptance in the language.

The title “Ms.” is used in either of two situations: (1) When you don’t know whether the woman is married or not, or (2) when she is a radical feminist and insists on being called by that title. It is already part of normal language, so I would guess you are reading a rather old article.
