Answer:
Knowledge about words, concepts, and language-based knowledge and facts.
Explanation:
Our long-term memory is made of different elements, one of these elements is Semantic memory, which is the part of the long-term memory that stores and processes ideas that don't have to do with our personal experience but rather they are general concepts about general and common knowledge like colors, sounds, countries, history, etc.
Therefore, semantic memory is knowledge about words, concepts, and language-based knowledge and facts.
