 The ancient Greek term ‘kategoria’ described what could be said against someone in a court of law, and indeed Aristotle uses what can be said of or in a subject as a route to distinguishing categories. There is controversy in the literature, however, about precisely how he arrived at his categories (Studtmann 2007). On one prominent interpretation, put forward by J. L. Ackrill, Aristotle arrived at his list of categories by way of distinguishing “different questions which may be asked about something” and noting “that only a limited range of answers can be appropriately given to any particular question” (Ackrill 1963, 78–9), e.g., the question ‘what is it’ can only be asked of a substance, and only answers describing substances are appropriate. The question ‘how much’, by contrast, requires a quantity for an answer, and so on.
