What is an isogloss in dialectology?

Options:

A rule that governs word order within a language
A line on a map marking where a particular linguistic feature changes geographically
A standardized written form used by a nation-state
A metric for measuring mutual intelligibility between languages

Correct answer: A line on a map marking where a particular linguistic feature changes geographically

Explanation: An isogloss is a geographic boundary separating where a linguistic feature is used versus not used; dialectologists have plotted isoglosses since surveys such as Georg Wenker's 1876 German dialect project.
