CON'CRETE, a. [L. concretus, from concresco, to grow together; con and cresco, to grow. See Grow.]

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. – Burnet.
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. – Watts. 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. – Bailey.
