  3. The process of lowering a liquid’s temperature beneath its usual point of freezing without causing it to solidify | a phenomenon where matter stays fluid even below freezing | a descriptor for temperatures so cold that physical traits of materials can change

Etymology: The story of "supercool" is a straightforward tale of scientific language blossoming in modern English. The term is a transparent compound, formed by combining the common prefix "super-"—meaning "above," "beyond," or "over"—with the adjective "cool." While the sense of "cool" as "low in temperature" has existed since Old English, the prefix "super-" comes from Latin, and has been used to intensify or amplify meanings in English since at least the 16th century. "Supercool" began to appear in scientific literature in the 18th and 19th centuries, describing the process by which a liquid is cooled below its normal freezing point without solidifying. This technical sense—the verb meaning "to cool a liquid below its freezing point without it becoming solid"—is the original and primary meaning. The adjective form, referring to substances that have been cooled in this way, followed naturally. Unlike many words that drift from technical jargon into metaphor, "supercool" has stayed relatively close to its scientific roots, though in recent decades it has occasionally been playfully repurposed to mean "very cool" or "extremely stylish" in informal speech, by analogy with the prefix's intensifying effect and the slang sense of "cool." However, this secondary sense is less established than the scientific one. The word’s construction is entirely transparent, with no hidden roots or surprising twists—just the building blocks of modern English applied to describe a fascinating physical phenomenon.
