Felix’s 53-year-old daughter, Lisa Smartt, kept track of his utterances, writing them down as she sat at his bedside in those final days. Smartt majored in linguistics at UC Berkeley in the 1980s and built a career teaching adults to read and write. Transcribing Felix’s ramblings was a sort of coping mechanism for her, she says. Something of a poet herself (as a child, she sold poems, three for a penny, like other children sold lemonade), she appreciated his unmoored syntax and surreal imagery. Smartt also wondered whether her notes had any scientific value, and eventually she wrote a book, Words on the Threshold, published in early 2017, about the linguistic patterns in 2,000 utterances from 181 dying people, including her father. [...] Many people die in such silence, particularly if they have advanced dementia or Alzheimer’s that robbed them of language years earlier. For those who do speak, it seems their vernacular is often banal. From a doctor I heard that people often say, “Oh fuck, oh fuck.” Often it’s the names of wives, husbands, children. “A nurse from the hospice told me that the last words of dying men often resembled each other,” wrote Hajo Schumacher in a September essay in Der Spiegel. “Almost everyone is calling for ‘Mommy’ or ‘Mama’ with the last breath.”
