Semantic knowledge refers to the understanding of meanings, concepts, and relationships between words and ideas. It encompasses facts, concepts, and the rules that govern how language is used. For example, knowing that the word dog refers to a specific type of animal and understanding its characteristics, such as being a pet or a companion, is part of semantic knowledge. This type of knowledge is essential for effective communication and comprehension. It allows individuals to make connections between different concepts, such as recognizing that cats and dogs are both types of pets. Semantic knowledge helps in learning, problem-solving, and navigating everyday situations.
