Originally, Mrs. was an abbreviation for mistress, the female counterpart of master. There were various spellings for both forms—it might be maistresse/maistre or maystres/mayster—and variation in pronunciation too. The word mistress had a more general meaning of a woman who is in charge of something. A governess in charge of children was a mistress, as was a woman head of a household. The abbreviated form was used most frequently as a title for a married woman.
Eventually, the title form took on a contracted, 'r'-less pronunciation, and by the end of the 18th century “missis” was the most acceptable way to say it. (A 1791 pronouncing dictionary said that to pronounce it "mistress" would “appear quaint and pedantic.”) The full word mistress had by then come to stand for a paramour, someone who was explicitly not a Mrs.
Sometimes a title is not an abbreviation for a word, but a word all of its own.
