What is the language in Yellowknife?

The official language of Yellowknife, like the rest of Canada, is English.

However, it's worth noting that:

* French is also an official language of Canada, and there is a small French-speaking community in Yellowknife.

* Indigenous languages are also present in Yellowknife, with many residents speaking languages like Dene (including Chipewyan, Slavey, and North Slavey), Inuinnaqtun, and Cree.

So, while English is the primary language in Yellowknife, there is a diverse linguistic landscape present in the city.
