There exists a fundamental difference in how today's Hopi youth are growing up from that of their parents and grandparents--Hopi youth are not acquiring the Hopi language. This sociolinguistic situation raises many questions about the vitality and continuity of the Hopi language.Two key findings emerged from the study of three Hopi young adults. First, the study showed that cultural experiences are key to developing a personal and cultural identity as Hopi, but a linguistic competence in Hopi, especially in ceremonial contexts, is fundamental to acquiring a complete sense of being Hopi. Secondly, the effect of modern circumstances apparent in behavior and attitude among Hopi is evidence of another shift--a move away from a collective maintenance of language as cultural practice to the maintenance of language and cultural practice as a personal choice of use.
