A pronoun is a word which takes the place of a noun. I, he, you, that, and who are among the pronouns.

Most of the declinable classes of words are constantly growing; that is, new words are being added to them. The pronoun class, however, contains only a limited number of words. In fact, there are a number of older form of pronouns such as thee, thou, and ye that can still be read and understood, but that are seldom used in modern writing.

The word pronoun, derived from the Latin pro meaning for and nomen meaning a name, applies to a limited number of words. Any noun may be represented by a pronoun.
The noun, the adjective, and the pronoun are intimately connected:

• A noun names an object.
• An adjective expresses properties of an object.
• A pronoun may take the place of the noun.

A verb is a word that expresses and affirms being, action, or state.

For example

The words be, read, sleep, and is loved in their normal uses are verbs.

Nothing is affirmed without a verb.

The word verb is derived from the Latin verbum meaning the word that is the important word. Verbs are a large class of words and phrases that express being, action, or state.
