Authorities from Minnesota to Maine are adding Native American language translations to road signs and building facades. The push is part of an effort in some places to revitalize Native languages and draw attention to the fact that Native communities live in these places or have lived there for centuries. Others are doing it to make Native American residents feel more welcome. A growing number of states have added dual language signs including Minnesota, Iowa, Wisconsin. Next year, Cambridge, Massachusetts, will add a Native American language to some street signs.
