 Liq·uid a.
 1. Flowing freely like water; fluid; not solid.
    Yea, though he go upon the plane and liquid water which will receive no step.   --Tyndale.
 2. Physics Being in such a state that the component molecules move freely among themselves, but have a definite volume changing only slightly with changes of pressure, and do not tend to separate from each other as the particles of gases and vapors do when the volume of the container is increased; neither solid nor gaseous; as, liquid mercury, in distinction from mercury solidified or in a state of vapor.
 Note: Liquid substances may form a definite interface with gases, whereas the molecules of different gases freely intermingle with each other.

 3. Flowing or sounding smoothly or without abrupt transitions or harsh tones. “Liquid melody.”
 4. Pronounced without any jar or harshness; smooth; as, l and r are liquid letters.
 5. Fluid and transparent; as, the liquid air.
 6. Clear; definite in terms or amount. [Obs.] “Though the debt should be entirely liquid.”
 Liquid glass. See Soluble glass, under Glass.
 Liq·uid, n.
 1. A substance whose parts change their relative position on the slightest pressure, and therefore retain no definite form; any substance in the state of liquidity; a fluid that is not gaseous and has a definite volume independent, of the container in which it is held. Liquids have a fixed volume at any given pressure, but their shape is determined by the container in which it is contained.  Liquids, in contrast to gases, cannot expand indefinitely to fill an expanding container, and are only slightly compressible by application of pressure.
 Note: ☞ Liquid and fluid are terms often used synonymously, but fluid has the broader signification. All liquids are fluids, but many fluids, as air and the gases, are not liquids.
 2. Phon. 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.
 Liquid measure, a measure, or system of measuring, for liquids, by the gallon, quart, pint, gill, etc.
