Parts of Speech

THE PARTS OF SPEECH
The eight parts of speech — verbs, nouns, pronouns, adverbs, adjectives, prepositions, conjunctions, and interjections — are defined on the pages hyperlinked below. (Some authorities would not list interjections, but would list determiners or articles, instead.) In addition, you can use the Powerpoint presentation on the Parts of Speech. Visit the page on Powerpoint for further information. The terms below — and over 300 others — are also listed in the Guide's INDEX.
Here's a little rhyme — by David B. Tower & Benjamin F. Tweed —that teachers used in days gone by to help students learn the parts of speech. (We include it here in response to popular demand. Why the song leaves out pronouns is a mystery. A writer from Richland, Washington, suggests "A PRONOUN replaces any noun: / he, she, it, and you are found. ) It has been set to music, but we'll leave that up to you to discover or create for yourself:
Three little words you often seeAre ARTICLES: a, an, and the.A NOUN's the name of anything,As: school or garden, toy, or swing.ADJECTIVES tell the kind of noun,As: great, small, pretty, white, or brown.VERBS tell of something being done: To read, write, count, sing, jump, or run.How things are done the ADVERBS tell, As: slowly, quickly, badly, well.CONJUNCTIONS join the words together,As: men and women, wind or weather.The PREPOSITION stands beforeA noun as: in or through a door.The INTERJECTION shows surpriseAs: Oh, how pretty!
