Final answer:
The Māori people of New Zealand are revitalizing their endangered indigenous language through immersion programs and language nests.
Step-by-step explanation:
An example of a society that is revitalizing its endangered indigenous language is the Māori people of New Zealand. The Māori language, also known as te reo Māori, was on the brink of extinction, but efforts have been made to restore and preserve it. The Māori have implemented programs such as the Te Kōhanga Reo immersion preschools and the Pūnana Leo language nests, where children are taught the language and culture by Māori elders. These immersion programs have been successful in creating fluent speakers of te reo Māori and ensuring its survival for future generations.
