Etymology
Origin of liquefy
First recorded in 1375–1425; late Middle English lyquefyen, from Old French liquefier, translation of Latin liquefacere “to melt” ( see liquefacient); see -fy
Explanation
When you turn a solid into a liquid, like when you set an ice cube in the sunshine and watch it melt into a puddle of water, you liquefy it. You can liquefy a solid by heating it until it melts, and you can also say the substance itself liquefies. A jar of coconut oil that's hard and solid in the refrigerator will liquefy if you leave it on the counter on a warm summer day. The Latin root of liquefy is liquefacere, "make liquid," from liquere, "be fluid," and facere, "to make."
