1. Literally, united in growth. Hence, formed by coalition of separate particles in one body; consistent in a mass; united in a solid form.

The first concrete state or consistent surface of the chaos.

2. In logic, applied to a subject; not abstract; as the whiteness of snow. Here whiteness is used as a concrete term, as it expresses the quality of snow.

Concrete terms, while they express the quality, do also express, or imply, or refer to a subject to which they belong.

A concrete number expresses or denotes a particular subject, as three men; but when we use a number without reference to a subject, as three, or five, we use the term in the abstract.

, v.t. To form a mass by the cohesion or coalescence of separate particles.
