Hale was known as a polyglot who retained the ability to learn new languages with extraordinary rapidity and perfection throughout his life. As a child in addition to English he learned both Spanish and Tohono O'odham. He learned Jemez and Hopi from his high school roommates and Navajo from his roommate at the University of Arizona. He became so fluent in Warlpiri that he raised his sons Ezra and Caleb to speak Warlpiri after his return from Australia to the United States. Ezra delivered his eulogy for his father in Warlpiri.
