Liquid


Definition:

  • (a.) Flowing freely like water; fluid; not solid.
  • (a.) Being in such a state that the component parts move freely among themselves, but do not tend to separate from each other as the particles of gases and vapors do; neither solid nor aeriform; as, liquid mercury, in distinction from mercury solidified or in a state of vapor.

  • (n.) A letter which has a smooth, flowing sound, or which flows smoothly after a mute; as, l and r, in bla, bra. M and n also are called liquids.
