What are the names used for Inuit language varieties in Greenland?

In Greenland, the Inuit language is collectively referred to as Greenlandic, which serves as an umbrella term for the dialects spoken on the island. These dialects are identified by the following names:1

• Kalaallisut: Also known as West Greenlandic, this is the most widely spoken dialect and is the sole official language of Greenland.123
• Tunumiit (or Tunumiisut): This dialect is spoken by the East Greenlandic population.13
• Inuktun (also referred to as Avanersuarmiutut, Polar Greenlandic, or Northern Greenlandic): This dialect is spoken by smaller groups, specifically in the Thule district.123

These varieties are part of the Eskimo-Aleut language family and exist as a dialect continuum, where linguistic differences increase with geographic distance.13
