Icelandic uses four characters that are not used in English : Ã 3\/4 ( thorn ) , ( like ` th ' in thin ) , Ã ( edh ) , ( like ` th ' in this ) , Ã ( pronounced like I ) and Ã ( pronounced like the french U ) . It can also be said that Ã is a `` softer '' version of Ã 3\/4 .
The Icelandic alphabet is notable for its retention of two old letters which no longer exist in the English alphabet : Ã , Ã 3\/4 ( Ã 3\/4 orn , anglicised as `` thorn '' ) and Ã , Ã ( eÃ , anglicised as `` eth '' or `` edh '' ) , representing the voiceless and voiced `` th '' sounds as in English thin and this respectively .
