Coming to words which we call names we find that the child will often extend a recognition-sign from one object to a second, and to our thinking widely dissimilar object through the discovery of some analogy. Such extension, moving rather along poetic lines than those of our logical classifications, is apt, as we have seen, to wear a quaint metaphorical aspect. A star, for example, looked at, I suppose, as a small bright spot, was called by one child an eye. The child M. called the opal globe of a lighted lamp a ‘moon’. ‘Pin’ was extended by another child to a crumb just picked up, a fly, and a caterpillar, and seemed to mean something little to be taken between the fingers. The same child used the sound ‘’at’ (hat) for anything put on the head, including a hair-brush. Another child used the word ‘key’ for other bright metal things, as money. Romanes’ child extended the word ‘star,’ the first vocable learned after ‘Mamma’ and ‘Papa,’ to bright objects generally, candles, gas-flames, etc. Taine speaks of a child of one year who after first applying the word “fafer” (from “chemin de fer”) to railway engines went on to transfer it to a steaming coffee-pot and everything that hissed or smoked or made a noise. In these last illustrations we have plainly a rudimentary process of classification. Any point of likeness, provided it is of sufficient interest to strike the attention, may thus serve as a basis of childish classification. As with names of things so with those of actions. The crackling noise of the fire was called by one child ‘barking,’ and the barking of a dog was named by another ‘coughing’. We see from this that the particular line of analogical extension followed by a child will depend on the nature of the first impressions or experiences which serve as his starting point. A like originality is apt to show itself in the first crude attempt to seize and name the relations of things. The child C. called dipping bread in gravy ‘ba’ (bath). Another child extended the word ‘door’ to “everything that stopped up an opening or prevented an exit, including the cork of a bottle, and the little table that fastened him in his high chair”. In these extensions we see the tendency of child-thought towards ‘concretism,’ or the use of a simple concrete idea in order to express a more abstract idea. Children frequently express the contrast big, little, by the pretty figurative language ‘Mamma’ and ‘baby’. Thus a small coin was called by an American child a ‘baby dollar’. Romanes’ daughter, named Ilda, pointed out the sheep in a picture as ‘Mamma-ba’ and the lambs as ‘Ilda-ba’. It is somewhat the same process when the child extends an idea obtained from the most impressive experience of childish difficulty, _viz._, ‘too big,’ so as to make it do duty for the abstract notion ‘too difficult’ in general.
