We do not mean to assert, that all verbs are literally derived from nouns in any language; because all languages have in process of time undergone such great variation; many nouns having become obsolete or have perished, and new verbs have been imported from foreign languages, or transplanted from ancient ones; but that this has originally been the construction of all verbs, as well as those to whip and to love above mentioned, and innumerable others.
Thus there may appear some difficulty in analyzing from what noun substantive were formed the verbs to stand or to lie; because we have not properly the name of the abstract ideas from which these verbs arose, except we use the same word for the participle and the noun substantive, as standing, lying. But the verbs, to sit, and to walk, are less difficult to trace to their origin; as we have names for the nouns substantive, a seat, and a walk.
But there is another verb of great consequence in all languages, which would appear, in its simplest form in our language to suggest but two primary ideas, as the verb to be, but that it suggests three primary ideas like other verbs maybe understood, if we use the synonymous term to exist instead of to be. Thus "I exist" suggests first the abstract idea of existence, not including the mode of existence, whether at rest, or in action, or in suffering; secondly it adds to that abstracted idea of existence its real state, or actual resting, acting, or suffering, existence; and thirdly the idea of the present time: thus the infinitive mood to be, and the participle, being, suggest both the abstract idea of existence, and the actual state of it, but not the time.
The verb to be is also used irregularly to designate the parts of time and actual existence; and is then applied to either the active or passive participles of other verbs, and called an auxiliary verb; while the mode of existence, whether at rest, or in action, or being acted upon, is expressed by the participle, as "I am loving" is nearly the same as "I love," amo; and "I am loved," amatus sum, is nearly the same as amor. This mode of application of the verb to be is used in French as well as in English, and in the passive voice of the Latin, and perhaps in many other languages; and is by its perpetual use in conversation rendered irregular in them all, as I am, thou art, he is, would not seem to belong to the infinitive mood to be, any more than sum, fui, sunt, fuerunt, appear to belong to esse.
The verb to have affords another instance of irregular application; the word means in its regular sense to possess, and then suggests three ideas like the above verb of existence: first the abstracted idea of the thing spoken of, or possession; secondly, the actual existence of possession, and lastly the time, as I have or possess. This verb to have like the verb to be is also used irregularly to denote parts of past time, and is then joined to the passive participles alone, as I have eaten; or it is accompanied with the passive participle of the verb to be, and then with the active participle of another verb, as I have been eating.
There is another word will used in the same irregular manner to denote the parts of future time, which is derived from the verb to will; which in its regular use signifies to exert our volition. There are other words used to express other circumstances attending upon verbs, as may, can, shall, all which are probably the remains of verbs otherwise obsolete. Lastly, when we recollect, that in the moods and tenses of verbs one word expresses never less than three ideas in our language, and many more in the Greek and Latin; as besides those three primary ideas the idea of person, and of number, are always expressed in the indicative mood, and other ideas suggested in the other moods, we cannot but admire what excellent abbreviations of language are thus achieved; and when we observe the wonderful intricacy and multiplicity of sounds in those languages, especially in the Greek verbs, which change both the beginning and ending of the original word through three voices, and three numbers, with uncounted variations of dialect; we cannot but admire the simplicity of modern languages compared to these ancient ones; and must finally perceive, that all language consists simply of nouns, or names of ideas, disposed in succession or in combination, all of which are expressed by separate words, or by various terminations of the same word.
Conclusion.
The theory of the progressive production of language in the early times of society, and its gradual improvements in the more civilized ones, may be readily induced from the preceding pages. In the commencement of Society the names of the ideas of entire things, which, it was necessary most frequently to communicate, would first be invented, as the names of individual persons, or places, fire, water, this berry, that root; as it was necessary perpetually to announce, whether one or many of such external things existed, it was soon found more convenient to add this idea of number by a change of termination of the word, than by the addition of another word.
As many of these nouns soon became general terms, as bird, beast, fish, animal; it was next convenient to distinguish them when used for an individual, from the same word used as a general term; whence the two articles a and the, in our language, derive their origin.
Next to these names of the ideas of entire things, the words most perpetually wanted in conversation would probably consist of the names of the ideas of the parts or properties of things; which might be derived from the names of some things, and applied to others which in these respects resembled them; these are termed adjectives, as rosy cheek, manly voice, beastly action; and seem at first to have been formed simply by a change of termination of their correspondent substantives. The comparative degrees of greater and less were found so frequently necessary to be suggested, that a change of termination even in our language for this purpose was produced; and is as frequently used as an additional word, as wiser or more wise.
