Similarities between Aymara and contiguous Quechua dialects have been considered by linguists simply as evidence of borrowing. This study, based on the application of standard comparative procedure to 520 Quechua sets and 255 Quechua-Aymara sets, gives evidence rather for genetic relationship between the two languages. A section on isoglosses clarifies the relationship between the northern and southern areas of the Quechua-speaking territory and proposes an older and important dialectal stage in central Peru.
