Around 65% of people living in Nunavut speak [[Inuktitut phrasebook|Inuktitut]] as a first language. Inuktitut is the traditional language spoken by the Inuit people, and is closely related to Greenlandic. It is a hard language to learn, and most people won’t even be able to read it because it is written in its own unique script. Though most Inuit probably speak English it would be a good idea to learn a few key phrases or bring a Inuktitut phrase book along. Learning the script in any case is actually relatively easy to do. French may also be useful though not necessary. In the more remote places Inuktitut may be necessary.
