A concrete concept—such as "apple," "chair," or "lightning"—is tethered to direct sensory experience. You can touch, see, or hear the referent. These concepts form the bedrock of early cognitive development because they rely on immediate environmental feedback.</p>
<p>Conversely, abstract concepts like "justice," "entropy," "democracy," or "infinity" lack a physical embodiment. They are constructed through complex networks of associations, linguistic agreements, and analogical reasoning.
