Answer:
<em>Textbook</em> 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: <em>textbook</em>. 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 <em>happiness</em>, <em>hunger</em>, and <em>satisfaction</em>. Taking all this into account, it can be said that <em>textbook</em> is an example of a concrete noun.
