- A state of matter characterized by having both a definite shape and a definite volume, and which tends to resist forces that tend to change said shape and volume. The atoms, molecules, or ions that compose solids are very close together, and are held firmly in place by intermolecular attraction which exceeds that of liquids. Matter in the solid state has little or no motion, and any movement of its constituent particles is usually confined to vibrations around a fixed position. Solids usually have a high density, and are either crystalline or amorphous. Solids can be distinguished from each other via characteristics such as density, hardness, malleability, and brittleness. The other physical states in which matter is known to exist are liquid, gas, plasma, and Bose-Einstein condensates. Also called solid state.

Origin & History of “solid”
Solid comes via Old French solide from Latin solidus ‘solid, whole’ (source also of English solder and soldier and of the French coin term sou). It went back to the same base (Indo-European *sol-) that produced Latin sollus ‘whole’ (source of English solemn and solicit) and salvus ‘unharmed’ (source of English safe, save, etc).
