when was the word ain't added to the dictionary
Ain't Webster's Third New International Dictionary, published in 1961, went against then-standard practice when it included the following usage note in its entry on ain't: "though disapproved by many and more common in less educated speech, used orally in most parts of the U.S. by many cultivated speakers esp. in the phrase ain't I."[35] Many commentators disapproved of the dictionary's relatively permissive attitude toward the word, which was inspired, in part, by the belief of its editor, Philip Gove, that "distinctions of usage were elitist and artificial."[36]
Nerd The first documented appearance of the word nerd is as the name of a creature in Dr. Seuss's book If I Ran the Zoo (1950), in which the narrator Gerald McGrew claims that he would collect "a Nerkle, a Nerd, and a Seersucker too" for his imaginary zoo.[3][5][6] The slang meaning of the term dates to the next year, 1951, when Newsweek magazine reported on its popular use as a synonym for drip or square in Detroit, Michigan.[7] By the early 1960s, usage of the term had spread throughout the United States, and even as far as Scotland.[8][9] At some point, the word took on connotations of bookishness and social ineptitude.[5]
