e. g., bird and peach; as back formations, e. g., beaut and flu as composition-forms, e. g., whatdyecallem; as picturesque compounds, e. g., booze-foundry; as onomatopes, e. g., biff and zowie; or in any other of the shapes that new terms take. If, by the chances that condition language-making, it acquires a special and limited meaning, not served by any existing locution, it enters into sound idiom and is presently wholly legitimatized; if, on the contrary, it is adopted by the populace as a counterword and employed with such banal imitativeness that it soon loses any definite significance whatever, then it remains slang and is avoided by the finical. An example of the former process is afforded by Tommy-rot. It first appeared as English schoolboy slang, but its obvious utility soon brought it into good usage. In one of Jerome K.

"I suppose you mean cant. No, I don't. Cant is something that you don't believe in yourself. It's Tommy-rot; there isn't any other word."

Nor was there any other satisfactory word for graft when it came in, nor for rowdy, nor for boom, nor for joy-ride, nor for omnibus-bill, nor for slacker, nor for trust-buster. Such words often retain a humorous quality; they are used satirically and hence appear but seldom in wholly serious discourse. But they have standing in the language nevertheless, and only a prig would hesitate to use them as Saintsbury used the best of the bunch and joke-smith.
On the other hand, many an apt and ingenious neologism, by falling too quickly into the gaping maw of the proletariat, is spoiled forthwith. Once it becomes, in Oliver Wendell Holmes' phrase, "a cheap generic term, a substitute for differentiated
