The Eight Basic Parts of Speech by William Balchar

William Balchar recognized prepositions as a distinct part of speech. He also included interjections like wow and ouch, but later English grammarians sometimes omitted that category. A participle is a verb that's used as an adjective, like the verb dancing. We use it as a verb when we say she is dancing, but we can also use it to describe a noun,. When we use it that way, it's called a participle. Adjectives are words that describe or modify a noun or pronoun - big, smart, fast, pretty; he didn't include them in his book.
