ناحیه همگرایی زبانی

Also known as linguistic area, area of linguistic convergence, diffusion area, language crossroads

A sprachbund ( , from , 'language federation'; or sprachbunds), also known as a linguistic area, area of linguistic convergence, or diffusion area, is a group of languages that share areal features resulting from geographical proximity and language contact. The languages may be genetically unrelated, or only distantly related, but the sprachbund characteristics might give a false appearance of relatedness.
