thumb|Isoglosses on the Faroe Islands
I don't have sufficient context provided to write an accurate overview of "isogloss." The image caption alone doesn't contain enough information about what an isogloss is, its definition, or why it matters. To write an accurate, sourced overview as requested, I would need additional context material explaining the concept.
