What does liquefied mean?
Liquefied means made liquid or transformed into a liquid state. The word is most often encountered as the past participle of the verb liquefy, as in “the butter liquefied in the warm pan,” but it also functions independently as an adjective before a noun. In everyday use, it usually describes a solid substance that has melted, softened, or otherwise become fluid. It can also convey the figurative idea that something has become weak, indistinct, or unable to retain a firm shape, although this extended use is less common. In technical and commercial contexts, liquefied is especially associated with gases converted into liquids for storage or transport, including liquefied natural gas and liquefied petroleum gas. The word is precise and generally neutral, combining a literal process with a specialized modern use. Understanding it is useful because it distinguishes a change of physical state from simply dissolving a substance in another liquid.

Liquefied natural gas makes natural gas easier to transport by turning it into a liquid that can travel by ship rather than only by pipeline.

Where does liquefied come from?
The word comes from the Latin verb liquefacere, meaning “to make liquid,” formed from liquidus, “liquid.” English borrowed the related forms liquefy and liquefaction in the 16th and 17th centuries. The suffix -ed in liquefied is the regular past-participle ending, and the form also came to be used attributively, especially in compounds describing gases converted into liquid form.
