30369 Southern Pomo 1-9 Southern Pomo is moribund. No child born after 1920 has learned the language, and as of 2012 there is only one confirmed fluent speaker and another speaker who maintains native phonology and spoke the language as a young man. The remaining speakers do not know each other, and Southern Pomo has therefore not been used as a medium of communication for decades. Though no one under 90 is fluent, there are scores of tribal members who learned dozens of words as children, and a subset of these words have been passed down to subsequent generations. (pp. 28-29.)
