(2.5) extreme tabooing in Aboriginal languages (Trask 1996):
a) In 1975 tribe member named Djäyila died, verb djäl- "want" became taboo, was replaced with duktuk- (borrowed from a neighbouring language)
b) In 1950 tribe member named Ngayunya died, pronoun ngayu "I" was tabooed and replaced by nganku; a subsequent death made nganku taboo, and therefore ngayu was revived
