1580s, abbreviation of mistress (q.v.), originally in all uses of that word. Prefixed to the name of a married woman by 1610s. The plural Mmes. is an abbreviation of French mesdames, plural of madame, used in English to serve as the plural of Mrs., which is lacking. Pronunciation "missis" was considered vulgar at least into 18c. (compare missus). The Mrs. "one's wife" is from 1920.
"the term of honour to a young girl" [Johnson], originally (17c.) a shortened form of mistress (compare Mrs., pronounced mis-ez). By 1640s as "prostitute, concubine." By 1700 as "a young, unmarried woman."
Misses as a trade term (originally in the mail order business) for sizes or styles of clothes for girls from about 10 to 17 years old is by 1880. Miss America is from 1922 as the title bestowed on the winner of an annual nationwide U.S. beauty/talent contest. Earlier it meant "young American women generally" or "the United States personified as a young woman," and it also was the name of a fast motor boat. In the 1811 reprint of the slang dictionary, Miss Laycock is given as an underworld euphemism for "the monosyllable."
"a ludicrous misuse of a big word," 1823, from the name of the theatrical character Mrs. Malaprop, who was noted for her blunders in the use of words (see malapropism). As an adjective, "out of place, inapt," by 1840. Related: Malapropian.
c. 1300, formal term of address to a lady (a woman of rank or authority, or the mistress of a household), from Old French ma dame, literally "my lady," from Latin mea domina (see Donna, and compare madonna). It became a conventional term of address to women of any degree (but chiefly to the married and matronly); also "a woman of fashion or pretension" (often with a suggestion of disparagement) by 1590s. From 1719 as "a courtesan, a prostitute;" the meaning "female owner or manager of a brothel" is attested by 1871.
The title of Madam is sometimes given here, and generally in Charleston (S. Carolina), and in the South, to a mother whose son has married, and the daughter-in-law is then called Mrs. By this means they avoid the inelegant phraseology of old Mrs. A., or the Scotch, Mrs. A senior. [Sir Charles Lyell, "A Second Visit to the United States of North America," 1849]
"gad about, spend time in frivolous pleasure-seeking, especially with the opposite sex," 1809, of uncertain origin, perhaps a playful elaboration of gallant in an obsolete verbal sense of "play the gallant, flirt, gad about." Related: Gallivanted; gallivanting.
Young Lobski said to his ugly wife,
"I'm off till to-morrow to fish, my life;"
Says Mrs. Lobski, "I'm sure you a'nt",
But you brute you are going to gallivant."
What Mrs. Lobski said was right,
Gay Mr. Lobski was out all night.
He ne'er went to fish, 'tis known very well
But where he went I shall not tell.
