It was National Indigenous Languages Day yesterday.
I studied the indigenous language of the region our house is in, Abenaki, at the Ndakinna Education Centre. Learning the indigenous language of our region lets settlers like me help keep the language alive; it also subsidizes classes for indigenous speakers.
Indigenous languages of North America can be very different in structure and vocabulary from European languages like English and French. I found the experience extremely challenging, and really mind-expanding. If your local indigenous community has language classes available to non-native people, I really recommend it.
It's also important to note that many indigenous communities consider their language a cultural treasure, and are not open to outsiders learning. Definitely use native-created materials and native-led courses if you are going to try to learn, to make sure you're using the treasure with respect and consent.
