Article, Noun, Adjective, Pronoun, Verb, Adverb, Preposition, and Conjunction."-- _Anthon's Valpy_, p.

With respect to our language, the plan of the Latin Accidence is manifestly inaccurate; nor can it be applied, without some variation, to the Greek.

In both, as well as in all other languages that have _Articles_, the best amendment of it, and the nearest adherence to it, is, to make the Parts of Speech _ten_; namely, the Article, the Noun, the Adjective, the Pronoun, the Verb, the Participle, the Adverb, the Conjunction, the Preposition, and the Interjection.

The best Latin grammarians admit that the Adjective ought not to be called a Noun; and the best Greek grammarians, that the Interjections ought not to be included among Adverbs.

With respect to Participles, a vast majority of grammarians in general, make them a distinct species, or part of speech; but, on this point, the English grammarians are about equally divided: nearly one half include them with the verbs, and a few call them adjectives.
