The third way in which the first words are learned is this: The idea and the word appear almost simultaneously, as in onomatopoetic designations and interjections. Absolutely original onomatopoetic words are very rare with children, and have not been observed by me except after the children already knew some words. The names of animals, _bow-wow_, _moo-moo_, _peep-peep_ (bird), _hotto_ (horse), from the expression of the carter, "hott-ho" ("_tt_," instead of _Haut_ (the skin), i. e., "left," in contrast with "aarr"--_Haar_, _Maehne_ (the mane)--i. e., "right"), are spoken for the child by the members of his family. Some names of animals, like _kukuk_ (cuckoo), also _kikeriki_ (cock) and _kuak_ (duck, frog), are probably formed often without having been heard from others, only more indistinctly, by German, English (American), and French children. _Ticktack_ (_tick-tick_) has also been repeated by a boy of two years for a watch. On the other hand, _weo-weo-weo_ (German, _[)u]io_) for the noise of winding a watch (observed by Holden in a boy of two years) is original. _Huet_, as an unsuccessful imitation of the locomotive-whistle by my boy of two and a half years, seems also noteworthy as an onomatope independently invented, because it was used daily for months in the same way merely to designate the whistle. The voice of the hen, of the redstart, the creaking of a wheel, were imitated by my child of his own accord long before he could speak a word. But this did not go so far as the framing of syllables. It is not easy in this to trace so clearly the framing of a concept as attaching itself directly to onomatopoetic forms as it is in a case communicated by Romanes. A child that was beginning to talk, saw and heard a duck on the water, and said _quack_. Thereafter the child called, on the one hand, all birds and insects, on the other hand, all liquids, _quack_. Finally, it called all coins also _quack_, after having seen an eagle on a French sou. Thus the child came, by gradual generalization, to the point of designating a fly, wine, and a piece of money by the same onomatopoetic word, although only the first perception contained the characteristic that gave the name.
