Word Origin and History for crystallike
Old English cristal "clear ice, clear mineral," from Old French cristal (12c., Modern French crystal), from Latin crystallus "crystal, ice," from Greek krystallos, from kryos "frost," from PIE root *kru(s)- "hard, hard outer surface" (see crust). Spelling adopted the Latin form 15c.-17c. The mineral has been so-called since Old English; it was regarded by the ancients as a sort of fossilized ice. As a shortened form of crystal-glass it dates from 1590s. As an adjective, from late 14c.
- A homogenous solid formed by a repeating, three-dimensional pattern of atoms, ions, or molecules and having fixed distances between constituent parts.
- A mineral, especially a transparent form of quartz that has a crystalline structure and is often characterized by external planar faces.
- A homogenous solid formed by a repeating, three-dimensional pattern of atoms, ions, or molecules and having smooth external surfaces with characteristic angles between them. Crystals can occur in many sizes and shapes.♦ The particular arrangement in space of these atoms, molecules, or ions, and the way in which they are joined, is called a crystal lattice. There are seven crystal groups or systems. Each is defined on the basis of the geometrical arrangement of the crystal lattice.
- A natural or synthetic material, such as quartz or ceramic, that consists of such crystals. When subjected to mechanical stresses, crystalline materials can generate an electric charge or, when subjected to an electric field, they can generate mechanical vibrations in what is known as the piezoelectric effect.
- An electrical device, such as an oscillator or a diode used for detecting radio signals, made of such a material.
