Hebrew has been a sleeping language for nearly two thousand years, however, between the late 19 century and the early 20 century, it was awakened to become a vernacular language. The success story of Hebrew language revitalization is the most cited example in the literature. It is often described as ”miraculous” rebirth from language death, or the only example of language revival. Using theory of language acquisition and micro language planning, this paper attempts to investigate the process and sociolinguistic factors contributing to the success of Hebrew language revitalization. Hebrew's experience not only show that endangered language can be saved, but also provide ways to awaken sleeping languages. Implications for Taiwan's language revitalization are provided.
