Etymology: Onycholysis is a medical coinage, built in New Latin from two Greek-derived parts. The first, "onycho-", comes from the Greek "onyx", which meant both "claw" and "fingernail" (and, separately, the gemstone onyx, whose name shares that root). The second, "-lysis", comes from the Greek "lysis", meaning loosening, dissolving or release, the same element found in words such as "analysis" and "paralysis". Put together, the term literally describes a loosening of the nail, which is exactly what happens when the nail detaches from the bed beneath it. Because it is a technical formation, no ancient Greek or Roman physician ever used this word. It was assembled by modern medical writers from classical building blocks, following the same pattern that produced many other clinical terms in English. Its value lies in precision: one word tells a clinician that the nail is lifting or separating from its underlying skin, without needing a longer description.
