Conradi[9] found that of 273 returns concerning children's pleasure in knowing or using new words, ninety-two per cent were affirmative, eight per cent negative, and fifty per cent gave words especially "liked." Some were partial to big words, some for those with z in them. Some found most pleasure in saying them to themselves and some in using them with others. In all there were nearly three hundred such words, very few of which were artificial. As to words pretty or queer in form or sound, his list was nearly as large, but the greater part of the words were different. Sixty per cent of all had had periods of spontaneously trying to select their vocabulary by making lists, studying the dictionary, etc. The age of those who did so would seem to average not far from early puberty, but the data are too meager for conclusion. A few started to go through the dictionary, some wished to astonish their companions or used large new words to themselves or their dolls. Seventy percent had had a passion for affecting foreign words when English would do as well. Conradi says "the age varies from twelve to eighteen, most being fourteen to sixteen." Some indulge this tendency in letters, and would like to do so in conversation, but fear ridicule. Fifty-six per cent reported cases of superfine elegance or affected primness or precision in the use of words. Some had spells of effort in this direction, some belabor compositions to get a style that suits them, some memorise fine passages to this end, or modulate their voices to aid them, affect elegance with a chosen mate by agreement soliloquize before a glass with poses. According to his curve this tendency culminates at fourteen. Adjectivism, adverbism, and nounism, or marked disposition to multiply one or more of the above classes of words, and in the above order, also occur near the early teens. Adjectives are often used as adverbial prefixes to other adjectives, and here favorite words are marked. Nearly half of Conradi's reports show it, but the list of words so used is small. [Illustration: Graph showing Slang, Reading Craze, and Precision by Age.] Miss Williams presents on interesting curve of slang confessed as being both attractive and used by 226 out of 251. From this it appears that early adolescence is the curve of greatest pleasure in its use, fourteen being the culminating year. There is very little until eleven, when the curve for girls rises very rapidly, to fall nearly us rapidly from fifteen to seventeen. Ninety-three out of 104 who used it did so despite criticism. Conradi, who collected and prints a long list of current slang words and phrases, found that of 295 young boys and girls not one failed to confess their use, and eighty-five per cent of all gave the age at which they thought it most common. On this basis he constructs the above curve, comparing with this the curve of a craze for reading and for precision in speech.
