Lyophobic

Part of speech: adjective

Definitions

1. Describing a condition in which certain substances show aversion to solvents, resulting in a poor ability to dissolve within them and limited compatibility with specific chemical environments
2. Characterizing materials that have a fundamental resistance to interaction with solvents, leading to their minimal solubility and reluctance to form solutions
3. Describing a property of substances that exhibit a strong dislike for solvents, thus resulting in reduced solubility and limited ability to interact with varied chemical media

Etymology: "Lyophobic" is a modern scientific coinage, built from two classical Greek elements. "Lyo-" comes from "lúō," meaning "to loosen" or "to dissolve," and "-phobic" comes from "phóbos," meaning "fear," with the Latin adjective ending "-icus" added on. Put together, the word describes something that shuns or is repelled by solvents. The "-phobic" element is the more familiar half. Words like "hydrophobic" follow the same pattern, with "hydro-" (water) joined to "-phobic" to describe substances that repel water. "Lyophobic" applies the same logic to solvents in general, so a lyophobic substance is one that resists dispersing into the liquid around it. The word is not ancient. Classical Greeks and Romans had no use for it, and the combination reflects the vocabulary of modern chemistry, which drew on Greek and Latin roots to name new concepts.

Synonyms: water-repellent, hydrophobic, nonwetting, repellent, insoluble
