Semantic memory is your store of general knowledge —facts, concepts, word meanings, and basic world information that you can recall without remembering when or where you learned it. It is different from episodic memory , which is about personal experiences and specific events.

Quick Scoop

Think of semantic memory as the brain’s knowledge library. It helps you know that Paris is the capital of France, that a “bachelor” means an unmarried man, or that birds are a type of animal.

Simple examples

  • Knowing 2 + 2 = 4.
  • Knowing what a tomato is.
  • Knowing the meaning of a word like “cat” or “justice”.
  • Knowing that the capital of France is Paris.

How it differs

Type| What it stores| Example
---|---|---
Semantic memory| Facts, concepts, meanings| Knowing that the Earth orbits the Sun 15
Episodic memory| Personal events and experiences| Remembering your last birthday party 15

Why it matters

Semantic memory supports language, reasoning, reading, and everyday understanding of the world. Researchers also study it because changes in semantic memory can show up in conditions like Alzheimer’s disease and semantic dementia.
