Quote from ‘Cambridge Lectures on Reasoning and the Logic of Things: Detached Ideas continued and the Dispute between Nominalists and Realists’
I distinguish verbs according to the numbers of their subject blanks, as medads, monads, dyads, triads, etc. A medad, or impersonal verb, is a complete assertion, like “It rains,” “you are a good girl.”
