Textbook is an example of a concrete noun.

Explanation:

There are two types of nouns: concrete nouns and abstract nouns. On the one hand, concrete nouns can be identified through one of the five senses (touch, sight, taste, hearing, or smell). Consider the following example: textbook. You can touch, smell, hear (if it falls), taste and see a textbook.

On the other hand, abstract nouns cannot be perceived by using one of the five senses. This is the case of happiness, hunger, and satisfaction. Taking all this into account, it can be said that textbook is an example of a concrete noun.
