Linguistic distance
Measure of how different one language is from another / From Wikipedia, the free encyclopedia
Linguistic distance is the measure of how different one language (or dialect) is from another.[1][2] Although they lack a uniform approach to quantifying linguistic distance between languages, linguists apply the concept to a variety of linguistic contexts, such as second-language acquisition, historical linguistics, language-based conflicts, and the effects of language differences on trade.[3][4][5][6][7][8][9]
