what are noun, adverb?

A noun is a "naming" word. A noun is a word for a person, place, or thing. Everything we can see or talk about is represented by a word that names it. That "naming" word is called a noun. Everything is represented by a word. This includes people (e.g., man, scientist), animals (e.g., dog, lizard), places (e.g., town, street), objects (e.g., vase, pencil), substances (e.g., copper, glass), qualities (e.g., heroism, sorrow), actions (e.g., swimming, dancing), and measures (e.g., inch, ounce). An adverb is a word used to modify a verb, an adjective, or another adverb. For example: She swims extremely quickly.(Here, the adverb extremely modifies the adverb quickly.) She is an extremely quick swimmer.(Here, the adverb extremely modifies the adjective quick.)
