Quechumaran or Kechumaran is a language-family proposal that unites Quechua and Aymara. Quechuan languages, especially those of the south, share a large amount of vocabulary with Aymara. The hypothesis of the existence of Quechuamara was originally posted by linguist Norman McQuown in 1955.[1]Terrence Kaufman[2] finds the proposal reasonably convincing, but Willem Adelaar, a Quechua specialist, believes the similarities to be caused by borrowing during long-term contact.[3]Lyle Campbell suspects that the proposal is valid but does not consider it to have been conclusively proved.[4]
Moulian et al. (2015) posits the Puquina language of the Tiwanaku Empire as a possible source for some of the shared vocabulary between Quechua, Aymara and Mapuche.[5]
An automated computational analysis (ASJP 4) by Müller et al. (2013)[6] also groups Quechuan and Aymaran together. However, since the analysis was automatically generated, the grouping could be either due to mutual lexical borrowing or genetic inheritance.
