Likewise, in SAE a period is required after most abbreviations of title so Mr., Mrs. Dr., Prof., etc. There is none after Miss because that is not an abbreviation. It is simply a word. MS. is conventionally written with a period after as well, as if it were an abbrevition, altho what exactly it’s supposed to be an abbreviation FOR is not clear. “MIZ”, as it pronounced, isn’t a word and Ms. is not short for mistress– Mrs. is. Again, if you’re an American, you can move on now to a more interesting issue, like why is peanut so-called when it is neither a pea, nor a nut.

In this case, I would say I prefer the UK standard in which there is no period placed after Mr, Mrs or Dr. It is simpler and the period seems entirely unnecessary. No one thinks mr is a word all by itself, or that D-R is how you spell the word doctor. BUT, since I write in SAE, I stuck with the period. I don’t make the rules, I try to follow them.

Mr.
Mrs.
Miss
Ms

That was in schools in Ft. Hood, Tx; Dallas, TX; Chicago, IL; and Indianapolis, IN.

I, too, agree with the British on this one, but ever since college, I’ve stuck to full-stoping “Ms” as well.

The one thing I learned in the military and took to heart was to not use periods after most of the words we were mandated in school to do so. Additionally, hyphens were used rarely.

We were taught “Air Force Effective Writing,” which implied that all the grammar rules drilled into us during our school years were not based on the language we actually speak but rather on Latin.

The instructors pointed out that English is Teutonic and not Latin. Maybe that’s why ending English sentences with a preposition or splitting infinitives sounds so much better than writing the way the grammar mavens dictate.
