This grammar worksheet helps students understand the difference between concrete and abstract nouns. First, they will review the definitions and examples of each type of noun and then use that knowledge to decode 12 sentences. In each sentence, the noun they need to identify as concrete or abstract is in bold and must be circled. Concrete nouns are things you can experience through your senses: touch, sight, hearing, smell, and taste. Dog, tree, apple, beach, and music are all concrete nouns because they can be seen, touched, smelled, tasted, or heard. Abstract nouns, on the other hand, are intangible. They refer to ideas, concepts, qualities, or states of being that cannot be seen, heard, touched, smelled, or tasted. For example, love, peace, beauty, knowledge, and time are all abstract nouns because they cannot be physically acted upon.
