But the main objection to the classification we are considering is not so much its want of absolute distinctness (a defect incident to all classification, in every department of science) as its one-sidedness: it is too much like the proverbial lover's division of the world into two parts, that where the beloved object is and that where she is not: it leaves almost all human tongues in one huge class together. Accordingly a much more popular and current system distinguishes three primary orders, separating the mass of inflectional languages into such as are agglutinative, or attach their formative elements somewhat loosely to a root which is not liable to variation; and such as are inflective, or unite more thoroughly their radical and formative elements, and make internal changes of the root itself bear their part, either primarily or secondarily, in the expression of grammatical relations. The distinction between these three orders is well expressed by Professor Max Müller in the following terms:—
"1. Roots may be used as words, each root preserving its full independence.
"2. Two roots may be joined together to form words, and in these compounds one root may lose its independence.
"3. Two roots may be joined together to form words, and in these compounds both roots may lose their independence."[1]
No better scheme of division, of a simple and comprehensive character, has yet been devised than this, and it is likely to maintain itself long in use. It faithfully represents, in the main, three successive stages in the history of language, three ascending grades of linguistic development. But its value must not be overrated, nor its defects passed without notice. In the first place, it does not include all the possible and actually realized varieties in the mode of formation of words. It leaves altogether out of account that internal change of vowels which, as was shown in the eighth lecture, is the characteristic and principal means of grammatical inflection in the Semitic tongues.
