L'alphabet islandais se distingue par le fait qu'il a conservé deux anciennes lettres qui n'existent plus dans l'alphabet anglais : Ã, Ã 3 \ / 4 -LRB- Ã 3 \ / 4 orn, anglicised as '' thorn '' -RRB- and Ã, Ã -LRB- eÃ, anglicised as '' eth '' or '' edh '' -RRB-, qui représente les sons "th '" voiceless and voiced "th' 'sounds as in English thin and this respectively.
Icelandic uses four characters that are not used in English : Ã 3 \ / 4 -LRB- thorn -RRB-, -LRB- like rythme 'in thin -RRB-, Ã -LRB- edh -RRB-, -LRB- like distth' in this -RRB-, Ã -LRB- prononcer like I -RRB- and Ã -LRB- prononcer like the french U -RRB-. It can also be said that Ã is a 'softer' version of Ã 3 \ / 4.
