| 词源 | Ff. Personal names beginning with a double f in English, such as Ffoulkes or Ffrench, originated as mistakes when the medieval or Old English capital F, which in script appears to be two small entwined f ’s, was transferred to print as two lower- case f ’s. No word in English should really begin with two f ’s. |
