IKU meaning in Regional ?

Inuktitut (; Inuktitut: [inuktiˈtut], syllabics ᐃᓄᒃᑎᑐᑦ; from inuk, "person" + -titut, "like", "in the manner of"), also Eastern Canadian Inuktitut, is one of the principal Inuit languages of Canada. It is spoken in all areas north of the tree line, including parts of the provinces of Newfoundland and Labrador, Quebec, to some extent in northeastern Manitoba as well as the Northwest Territories and Nunavut. It is one of the aboriginal languages written with Canadian Aboriginal syllabics.

It is recognised as an official language in Nunavut alongside Inuinnaqtun, and both languages are known collectively as Inuktut. Further, it is recognized as one of eight official native tongues in the Northwest Territories. It also has legal recognition in Nunavik—a part of Quebec—thanks in part to the James Bay and Northern Quebec Agreement, and is recognised in the Charter of the French Language as the official language of instruction for Inuit school districts there. It also has some recognition in Nunatsiavut—the Inuit area in Labrador—following the ratification of its agreement with the government of Canada and the province of Newfoundland and Labrador. The 2016 Canadian Census reports that there are 65,030 Indigenous individuals who identify themselves as Inuit of which 35,215 self-reported Inuktitut as their mother tongue.

The term Inuktitut is often used more broadly to include Inuvialuktun and thus nearly all the Inuit dialects of Canada. However, Statistics Canada lists Inuvialuktun with Inuinnaqtun in the Canadian Census.
