It is true that the variety of the modes by which a given sound may be represented is not so great in all words as it is in these examples, though with respect to a vast number of the words in common use the above are fair specimens. They were not specially selected, but were taken almost at random. And there are very few words in the language the sound of which might not be represented by several different modes.
Take, for example, the three last words of the last sentence, which, as the words were written without any thought of using them for this purpose, may be considered, perhaps, as a fair specimen of words taken actually at random. The sound of the word several might be expressed in perfect accordance with the usage of English spelling, as ceveral, severul, sevaral, cevural, and in many other different modes. The combinations dipherant, diferunt, dyfferent, diffurunt, and many others, would as well represent the sound of the second word as the usual mode. And so with modes, which, according to the analogy of the language, might as well be expressed by moads, mowdes, moades, mohdes, or even mhodes, as in Rhodes.
An exceptionally precise speaker might doubtless make some slight difference in the sounds indicated by the different modes of representing the same syllable as given above; but to the ordinary appreciation of childhood the distinction in sound between such combinations, for example, as a n t in constant and e n t in different would not be perceptible.
Now, when we consider the obvious fact that the child has to learn mechanically, without any principles whatever to guide him in discovering which, out of the many different forms, equally probable, judging simply from analogy, by which the sound of the word is to be expressed, is the right one; and considering how small a portion of his time each day is or can be devoted to this work, and that the number of words in common use, all of which he is expected to know how to spell correctly by the time that he is twelve or fifteen years of age, is probably ten or twelve thousand (there are in Webster’s dictionary considerably over a hundred thousand); when we take these considerations into account, it would seem that a parent, on finding that a letter written by his daughter, twelve or fourteen years of age, has all but three or four words spelled right, ought to be pleased and satisfied, and to express his satisfaction for the encouragement of the learner, instead of appearing to think only of the few words that are wrong, and disheartening and discouraging the child by attempts to make her ashamed of her spelling.
