3. A third class of adjectives includes what are termed Participles, which are allied to the infinitive moods of verbs, and are formed in our language by the addition only of the syllable ing or ed; and are of two kinds, active and passive, as loving, loved, from the verb to love. The verbs suggest an idea of the noun, or thing spoken of; and also of its manner of existence, whether at rest, in action, or in being acted upon; as I lie still, or I whip, or I am whipped; and, lastly, another idea of the time of resting, acting, or suffering; but these adjectives called participles, suggest only two primary ideas, one of the noun, or thing spoken of, and another of the mode of existence, but not a third idea of time; and in this respect participles differ from the verbs, from which they originate, or which originated from them, except in their infinitive moods.
Nor do they resemble adjectives only in their suggesting but two primary ideas; but in the Latin and Greek languages they are declined through all the cases, genders, and numbers, like other adjectives; and change their terminations in the degrees of comparison.
In our language the participle passive, joined to the verb to be, for the purpose of adding to it the idea of time, forms the whole of the passive voice; and is frequently used in a similar manner in the Latin language, as I am loved is expressed either by amor, or amatus sum. The construction of the whole passive voice from the verb to be and the participles passive of other verbs, contributes much to the simplicity of our language, and the ease of acquiring it; but renders it less concise than perhaps it might have been by some simple variations of termination, as in the active voice of it.
4. A fourth kind of adjective is called by the grammarians an Adverb; which has generally been formed from the first kind of adjectives, as these were frequently formed from correspondent substantives; or it has been formed from the third kind of adjectives, called participles; and this is effected in both cases by the addition, of the syllable ly, as wisely, charmingly.
This kind of adjective suggests two primary ideas, like the adjectives, and participles, from which they are derived; but differ from them in this curious circumstance, that the other adjectives relate to substantives, and are declined like them in the Latin and Greek languages, as a lovely boy, a warlike countenance; but these relate to verbs, and are therefore undeclined, as to act boldly, to suffer patiently.
IV. Verbs.
The fourth class of words consists of those which are termed Verbs, and which in their simplest state suggest three ideas; first an idea of the noun, or name of the thing spoken of, as a whip. 2. An idea of its mode of existence, whether at rest, or in action, or in being acted upon. 3. An idea of the time of its existence. Thus "the beadle whipped the beggar," in prolix language might be expressed, the beadle with a whip struck in time past the beggar. Which three ideas are suggested by the one word whipped.
Verbs are therefore nouns, or names of intire ideas, with the additional ideas of their mode of existence and of time; but the participles suggest only the noun, and the mode of existence, without any idea of time; as whipping, or whipped. The infinitive moods of verbs correspond in their signification with the participles; as they also suggest only the noun, or name of the thing spoken of, and an idea of its mode of existence, excluding the idea of time; which is expressed by all the other moods and tenses; whence it appears, that the infinitive mood, as well as the participle, is not truly a part of the verb; but as the participle resembles the adjective in its construction; so the infinitive mood may be said to resemble the substantive, and it is often used as a nominative case to another verb.
Thus in the words "a charming lady with a smiling countenance," the participle acts as an adjective; and in the words "to talk well commands attention," the infinitive mood acts as the nominative case of a noun substantive; and their respective significations are also very similar, as whipping, or to whip, mean the existence of a person acting with a whip.
In the Latin language the verb in its simplest form, except the infinitive mood, and the participle, both which we mean to exclude from complete verbs, suggests four primary ideas, as amo, suggests the pronoun I, the noun love, its existence in its active state, and the present time; which verbs in the Greek and Latin undergo an uncounted variation of termination, suggesting so many different ideas in addition to the four primary ones.
