The deficiency in true conjunctions and relative pronouns is met in many American languages by a reversal of the plan of expression with us. The relative clause becomes the principal one. There is a certain logical justice in this; for, if we reflect, it will appear evident that the major proposition is, in our construction, presented as one of the conditions of the minor. “I shall drown, if I fall in the water,” means that, of the various results of my falling in the water, one of them will be that I shall drown. “I followed the road which you described,” means that you described a road, and one of the results of this act of yours was that I followed it. This explains the plan of constructing compound sentences in Qquichua. Instead of saying “I shall follow the road which you describe,” the construction is “You describe, this road I shall follow;” and instead of “I shall drown if I fall in the water,” it would be, “I fall in the water, I shall drown.” The Mexican language introduces the relative clause by the word _in_, which is an article and demonstrative pronoun, or, if the proposition is a conditional one, by _intla_, which really signifies “within this,” and conveys the sense that the major is included within the conditions of the minor clause. The Cakchiquel conditional particle is _vue_, if, which appears to be simply the particle of affirmation “yes,” employed to give extension to the minor clause, which, as a rule, is placed first. Or a conventional arrangement of words may be adopted which will convey the idea of certain dependent clauses, as those expressing similitude, as is often the case in Mexican. § 15. THE DUAL IN AMERICAN LANGUAGES. In his admirable philosophical examination of the dual number in language, Humboldt laid the foundation of a linguistic theory of numerals which has not yet received the development it merits. Here he brings into view the dual and plural endings of a list of American languages, and explains the motives on which they base the inclusive and exclusive plurals so common among them. It is, in fact, a species of pronominal dual confined to the first person in the plural. This, he goes on to say, is by no means the only dual in these tongues. Some of them express both the other classes of duals which he names. Thus, the Totonaca has duals for all objects which appear as pairs in nature, as the eyes, the ears, the hands, etc.; while the Araucanian equals the Sanscrit in extending the grammatical expression of the dual through all parts of speech where it can find proper application.[27-*] § 16. HUMBOLDT’S ESSAY ON THE AMERICAN VERB. The essay on the American verb translated in the following pages has never previously appeared in print, either in German or English. The original MS. is in the Royal Library at Berlin, whence I obtained a transcript. The author alludes to this essay in several passages of his printed works, most fully in his “Letter to M. Abel-Remusat” (1826), in which he says:
