The Inuit language, or Inuktut, is a dialect continuum spoken in the North American Arctic: in the north of Alaska, the Northwest Territories, Nunavut, Nunavik (Arctic Quebec), in Nunatsiavut (in Labrador), and in Greenland. Inuktitut refers to the eastern Canadian dialect group.

Inuktut is a polysynthetic langage, which means that its words can attain a complexity similar to full clauses in other languages.
