Part 555

Syn. -- 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.
