The Icelandic alphabet is a Latin-script alphabet including some letters duplicated with acute accents; in addition, it includes the letter eth (), transliterated as "d", and the runic letter thorn (), transliterated as "th" (see picture); and are considered letters in their own right and not a ligature or diacritical version of their respective letters. Icelanders call the ten extra letters (not in the English alphabet), especially thorn and eth, ("specifically Icelandic" or "uniquely Icelandic"), although they are not. Eth is also used in Faroese and Elfdalian, and while thorn is no longer used in any other living language, it was used in many historical languages, including Old English. Icelandic words never start with , which means the capital version is mainly just used when words are spelled using all capitals.
