tangible

The word bridges the gap between physical sensation and intellectual certainty. In its most literal sense, it describes things that can be physically felt, often used to describe atmosphere or weather (e.g., "tangible tension") where an abstract feeling becomes so intense it feels like a physical object.

In professional or political contexts, it shifts toward the idea of proof and results. It is the opposite of 'theoretical' or 'speculative'. When someone asks for tangible evidence, they aren't just asking for truth; they are asking for something concrete that can be measured, seen, or pointed to.

Compared to 'concrete', 'tangible' often carries a stronger connotation of accessibility and immediate perception. While something concrete is solid, something tangible is specifically graspable.
