Siphuthi (10746) = Vulnerable (80 percent certain, based on the evidence available) (While preconditions exist for the language to begin the slide towards obsolescence and death, Phuthi has not yet begun to do this in a significant way... Children playing outside speak almost exclusively Phuthi with one another... children acquire Phuthi first and often do not command Sotho and Xhosa until they begin going to school.)
