Words, when used in sentences, are divided into eight classes, called Parts of Speech. They are called parts of speech because our talk is not made up of any one class of words. In our speech we put different kinds together. The classes are called nouns, pronouns, verbs, adjectives, adverbs, conjunctions, prepositions, and interjections. In this chapter you are to study two parts of speech.
