Through this manifold significance of a word, which is a substitute for a whole sentence, is exhibited a much higher activity of the intellect than appears in the mutilation and new formation of words having but one meaning to designate a sense-impression, for, although in the latter is manifested the union of impressions into perceptions and also of qualities into concepts, wherein an unconscious judgment is involved, yet a _clear_ judgment is not necessarily connected with them. The union of concepts into conscious clear judgments is recognized rather in the formation of a sentence, no matter whether this is expressed by one word or by several words. In connection with this an error must be corrected that is wide-spread. It consists in the assumption that all children begin to speak with nouns, and that these are followed by verbs. This is by no means the case. The child daily observed by me used an adjective for the first time in the twenty-third month in order to express a judgment, the first one expressed in the language of those about him. He said "hot" for "The milk is too hot." In general, the appropriation and employment of words for the first formation of sentences depends, in the first instance, upon the action of the adults in the company of the child. A good example of this is furnished by an observation of Lindner, whose daughter in her fourteenth month first begged with her hands for a piece of apple, upon which the word "apple" was distinctly pronounced to her. After she had eaten the apple she repeated the request, re-enforcing her gesture this time by the imitated sound _appn_, and her request was again granted. Evidently encouraged by her success, the child from that time on used _appn_ for "eat, I want to eat," as a sign of her desire to eat in general, because those about her "accepted this signification and took the word stamped by her upon this concept for current coin, else it would very likely have been lost." This also confirms my statement (p. 85) that a child easily learns to speak with logical correctness with wrong words. He also speaks like the deaf-mute with logical correctness with quite a different arrangement of words from that of his speech of a later period. Thus the child just mentioned, in whom "the inclination to form sentences was manifest from the twenty-second month," said, "hat die Olga getrinkt," when she had drunk!
