Here's why:
* Concreteness is relative: A "rock" is more concrete than "love," but less concrete than "this rock."
* Context matters: "Chair" might be more concrete than "justice" in a conversation about furniture, but less concrete than "justice" in a philosophical debate.
* Subjectivity exists: Personal experiences and cultural background can influence how concrete a noun feels.
To determine concreteness, we need to consider:
1. The noun itself: How tangible and specific is the noun?
2. The context: What is being discussed or described?
Example:
* "Apple" is more concrete than "fruit" because it refers to a specific type of fruit.
* "Chair" is more concrete than "furniture" because it refers to a specific piece of furniture.
* "Red" is more concrete than "color" because it refers to a specific color.
Instead of trying to find the most concrete noun, it's more helpful to understand how concreteness functions in language and how it impacts meaning.
