Of the thousands of patients with aphasia whom we have studied in our fifty combined years of neurological practice, one of the most interesting was a 44-year-old man, whom we refer to as Rufo, who, following a seemingly-minor blow to his head, developed a highly-specific expressive aphasia: he lost the ability to utter the word four. The logological implications of the case might interest the readers of Word Ways.
