Cusco–Collao or Qusqu–Qullaw (Quechua) is a collective term used for Quechua dialects that have aspirated and ejective plosives, apparently borrowed from Aymaran languages. They include Cusco Quechua, Puno Quechua, North Bolivian Quechua, and South Bolivian Quechua. Together with Ayacucho Quechua, which is mutually intelligible, they form the Southern Quechua language.
