Note 198 — THE EIGHTH STORY
John Payne translation
The plural of a surname is, in strictness, always used by the Italians in speaking of a man by his full name, dei being understood between the Christian and surname, as Benedetto (dei) Ferondi, Benedict of the Ferondos or Ferondo family, whilst, when he is denominated by the surname alone, it is used in the singular, il (the) being understood, e.g. (Il) Boccaccio, (Il) Ferondo, i.e. the particular Boccaccio or Ferondo in question for the nonce.
