MASHPEE, Mass. (AP) — The Massachusetts tribe whose ancestors shared a Thanksgiving meal with the Pilgrims nearly 400 years ago is reclaiming its long-lost language, one schoolchild at a time. "Weesowee mahkusunash," says teacher Siobhan Brown, using the Wampanoag phrase for "yellow shoes" as she reads to a preschool class from Sandra Boynton's popular children's book "Blue Hat, Green Hat." The Mukayuhsak Weekuw — or "Children's House " — is an immersion school launched by the Cape Cod-based Mashpee Wampanoag tribe, whose ancestors hosted a harvest celebration with the Pilgrims in 1621 that helped form the basis for the country's Thanksgiving tradition.
