You put a period after all of those in the states, however, the British system requires no period after such abbreviations, Mr Mrs Ms .
Yes, i.e. Mr. , Mrs.
Yes, Mrs. has a period because it is an abbreviation and mrs is not a word. The same holds true for Mr., Dr., and Ms.
Yes, the general rule is that where a word is abbreviated it is followed by a full stop to indicate this. For instance Mr. is an abbreviation of Mister.
Punctuation after Ms is optional. ======================== I disagree. Punctuation following Mr and Mrs is becoming optional, but I would respectfully submit that it is incorrect to place a period after Ms, because Ms is actually a word and not an abbreviation (as are Mr, for Master, and Mrs, for Mistress).
You put Mrs. when someone is married and you put Ms. when some one is not married.
After all titles for example: Mr. Mrs. Dr. Rev. Ms.,etc.
Ms
Yes there should be a period.
Ms. is pronounced "Miss" and Mrs. is pronounced "Misses". You pronounce "Ms" as "Miz" and pronounce "Mrs" as "Miss-es"
Ms., Miss, Mr., and Mrs. are all honorific abbreviations. Ms. can be used for a single or married woman. Miss is reserved for single women who have never been married. Mr. is used for an adult man and Mrs. is used for a married or widowed woman.
Yes there is.
