concrete
word
Definition
As a noun, concrete is a hard building material made by mixing cement, sand, small stones, and water. As an adjective, it means specific, real, and clear rather than general or abstract.
Usage & Nuances
Very common in both everyday and academic English. As a material noun, it is usually uncountable: 'The wall is made of concrete.' As an adjective, it often appears in phrases like 'concrete evidence', 'concrete example', and 'concrete plan'. Do not confuse it with 'specific': 'concrete' stresses something tangible or clearly defined, while 'specific' mainly stresses precision.
