The process of wearing away or eroding while radiating or spreading outward.
From 'corradiate' plus the suffix '-ion,' which forms abstract nouns from verbs indicating an action or process. This rare term combines 'corrade' (to erode) with 'radiation' (spreading outward).
Like 'corradiate,' this word lives in a gray zone—it's theoretically constructible from English word-building rules, but it's so rare that it barely exists in actual use, showing how language communities collectively decide which potential words are worth keeping.
