Homonym: Rarity (Scarcity)
Rarity refers to how uncommon or unique something is. When an item is rare, it means there are very few of them available, making it special or valuable. For example, a rare coin might be sought after by collectors because only a limited number were made. This uniqueness often increases its worth and desirability.
In nature, rarity can also apply to species. A rare animal or plant may be endangered, meaning it is at risk of disappearing. Conservation efforts are often put in place to protect these rare species, highlighting their importance in maintaining biodiversity and the health of ecosystems.
