Icelandic orthography

Eth
Thorn
A handwriting extract; the Icelandic letters ⟨ð⟩ and ⟨þ⟩ are visible.

Icelandic orthography uses a Latin-script alphabet which has 32 letters. Compared with the 26 letters of English, the Icelandic alphabet lacks C, Q, W and Z, but additionally has Ð, Þ, Æ and Ö. Six letters have forms with acute accents to produce Á, É, Í, Ó, Ú and Ý.

The letters Eth (⟨ð⟩, capital ⟨Ð⟩), transliterated as ⟨d⟩, and Thorn (⟨þ⟩, capital ⟨Þ⟩), transliterated as ⟨th⟩, are widely used in the Icelandic language. Eth is also used in Faroese and Elfdalian, while thorn was used in many historical languages such as Old English. The letters ⟨æ⟩ (capital ⟨Æ⟩) and ⟨ö⟩ (capital ⟨Ö⟩) are considered as completely separate letters in Icelandic, and are collated as such, even though they originated as a ligature and a diacritical version respectively.

Icelandic words never start with ⟨ð⟩, which means its capital ⟨Ð⟩ occurs only when words are spelled in all capitals. The alphabet is as follows:

Majuscule forms (also called uppercase or capital letters)
A Á B D Ð E É F G H I Í J K L M N O Ó P R S T U Ú V X Y Ý Z Þ Æ Ö
Minuscule forms (also called lowercase or small letters)
a á b d ð e é f g h i í j k l m n o ó p r s t u ú v x y ý z þ æ ö

The above table has 33 letters, including the letter Z which is obsolete but may be found in older texts, e.g. verzlun became verslun.

The names of the letters are grammatically neuter (except the now obsolete ⟨z⟩ which is grammatically feminine).

The letters ⟨a⟩, ⟨á⟩, ⟨e⟩, ⟨é⟩, ⟨i⟩, ⟨í⟩, ⟨o⟩, ⟨ó⟩, ⟨u⟩, ⟨ú⟩, ⟨y⟩, ⟨ý⟩, ⟨æ⟩ and ⟨ö⟩ are considered vowels, and the remainder are consonants.

⟨c⟩ (, [sjɛː]), ⟨q⟩ (, [kʰuː]) and ⟨w⟩ (tvöfalt vaff, [ˈtʰvœːfal̥t ˌvafː]) are only used in Icelandic in words of foreign origin and some proper names that are also of foreign origin. Otherwise, ⟨c⟩, ⟨qu⟩, and ⟨w⟩ are replaced by ⟨k/s/ts⟩, ⟨hv⟩, and ⟨v⟩ respectively. (In fact, ⟨hv⟩ etymologically corresponds to Latin ⟨qu⟩ and English ⟨wh⟩ in words inherited from Proto-Indo-European: Icelandic hvað, Latin quod, English what.)

⟨z⟩ (seta, [ˈsɛːta]) was used until 1973, when it was abolished, as it was only an etymological detail. It originally represented an affricate [t͡s], which arose from the combinations ⟨t⟩+⟨s⟩, ⟨d⟩+⟨s⟩, ⟨ð⟩+⟨s⟩; however, in modern Icelandic it came to be pronounced [s], and since it was a letter that was not commonly used, it was decided in 1973 to replace all instances of ⟨z⟩ with ⟨s⟩.[2] However, one of the most important newspapers in Iceland, Morgunblaðið, still uses it sometimes (although very rarely), a hot-dog chain, Bæjarins Beztu Pylsur, and a secondary school, Verzlunarskóli Íslands have it in their names. It is also found in some proper names (e.g. Zakarías, Haralz, Zoëga), and loanwords such as pizza (also written pítsa). Older people who were educated before the abolition of the ⟨z⟩ sometimes also use it.

While ⟨c⟩, ⟨q⟩, ⟨w⟩, and ⟨z⟩ are found on the Icelandic keyboard, they are rarely used in Icelandic; they are used in some proper names of Icelanders, mainly family names (family names are the exception in Iceland). ⟨c⟩ is used on road signs (to indicate city centre) according to European regulation, and cm is used for the centimetre according to the international SI system (while it may be written out as sentimetri). Many[who?] believe these letters should be included in the alphabet, as its purpose is a tool to collate (sort into the correct order), and practically that is done, i.e. computers treat the alphabet as a superset of the English alphabet. The alphabet as taught in schools up to about 1980[citation needed] has these 36 letters (and computers still order this way): a, á, b, c, d, ð, e, é, f, g, h, i, í, j, k, l, m, n, o, ó, p, q, r, s, t, u, ú, v, w, x, y, ý, z, þ, æ, ö.
