liquid

Definitions

General English

Accounting

  • adjective easily converted to cash, or containing a large amount of cash

Electronics

  • A state of matter which is approximately intermediate between a gas and a solid. Liquids have a definite volume, like a solid, yet have the tendency to assume the shape of its container, like a gas. A liquid will only occupy the proportion of its container which equals the volume of the liquid, and will seek the lowest level. That is, it will not expand to occupy all the available space, as a gas would. The atoms or molecules composing a liquid have enough thermal energy to move freely, but also have significant intermolecular attraction. Liquids are very hard to compress, and when cooled sufficiently are converted into a solids, while when heated sufficiently into gases. The other physical states in which matter is known to exist are solid (1), gas, plasma, and Bose-Einstein condensates.

Origin & History of “liquid”

Latin liquēre meant ‘be fluid’. From it was derived the adjective liquidus, which reached English via Old French (it was not used as a noun in the sense ‘liquid substance’ until the early 18th century). also derived from liquēre was the noun liquor, which passed into Old French as licur or licour. English has borrowed this twice: first in the 13th century as licour, which was subsequently ‘re-latinized’ as liquor, and then in the 18th century in the form of its modern French descendant liqueur. From the same ultimate source come liquefy (16th c.), liquidate (16th c.) (which goes back to a metaphorical sense of Latin liquēre, ‘be clear’ – thus ‘clear a debt’; the modern meaning ‘destroy’ was directly inspired by Russian likvidirovat’), and the final syllable of prolix(15th c.).
