Not hollow; full of matter; as, a solid globe or cone, as distinguished from a hollow one; not spongy; dense; hence, sometimes, heavy. 3. <mathematics> Having all the geometrical dimensions; cubic; as, a solid foot contains 1,728 solid inches. In this sense, cubics now generally used. 4. Firm; compact; strong; stable; unyielding; as, a solid pier; a solid pile; a solid wall. 5. Applied to a compound word whose parts are closely united and form an unbroken word; opposed to hyphened. 6.

Synonym: Hard, firm, compact, strong, substantial, stable, sound, real, valid, true, just, weighty, profound, grave, important. Solid, Hard. These words both relate to the internal constitution of bodies; but hardnotes a more impenetrable nature or a firmer adherence of the component parts than solid. Hard is opposed to soft, and solid to fluid, liquid, open, or hollow. Wood is usually solid; but some kinds of wood are hard, and others are soft. "Repose you there; while I [return] to this hard house, More harder than the stones whereof 't is raised."
