That the noun and verb are the only parts of speech, absolutely necessary for a communication of ideas among rude nations, will be obvious to any person who considers their manner of life, and the small number of their necessary ideas. Their employments are war and hunting; and indeed some tribes are so situated as to have no occupation but that of procuring subsistence. How few must be the ideas of a people, whose sole employment is to catch fish, and take wild beasts for food! Such nations, and even some much farther advanced towards civilization, use few or no prepositions, adverbs and conjunctions, in their intercourse with each other, and very few adjectives. Some tribes of savages in America use no adjectives at all; but express qualities by a particular form of the verb; or rather blend the affirmation and quality into one word.[86] They have, it is said, some connecting words in their own languages, some of which have advanced towards copiousness and variety. But when they attempt to speak English, they use nouns and verbs long before they obtain any knowlege of the particles. They speak in this manner, go, way---- sun, shine---- tree, fall---- give, Uncas, rum; with great deliberation and a short pause between the words. They omit the connectives and the abbreviations, which may be called the "wings of Mercury." Thus it is evident, that, among such nations, a few nouns and verbs will answer the purposes of language. Many of this kind of expressions remain in the English language to this day. _Go away_ is the savage phrase with the article _a_, derived perhaps from _one_, or what is more probable, added merely to express the sound, made in the transition from one word to the other, for if we attend to the manner in which we pronounce these or two similar words, we shall observe that we involuntarily form the sound expressed by _a_ or _aw_. In some such manner are formed _astray_, _awhile_, _adown_, _aground_, _ashore_, _above_, _abaft_, _among_, and many others. They are usually called adverbs and prepositions; but they are neither more nor less than nouns or verbs, with the prefix _a_.[87] That all the words called adverbs and prepositions, are derived in like manner, from the principal parts of language, the noun and verb, is not demonstrable; but that _most_ of them are so derived, etymology clearly proves.
