svidning

Could you specify the language or field for "svidning"? It does not correspond to a widely known English concept, and I want to ensure accuracy. For example, is it a Scandinavian term related to history or culture, a technical term in a particular discipline (such as metallurgy or botany), or a place name? If you provide the context, I can draft a concise, neutral wiki-style article (under 300 words).
