Eth

Eth (Ð, ð; also spelled edh or eð) is a letter used in Old English, Icelandic, Faroese (in which it is called edd), and Elfdalian. It was also used in Scandinavia during the Middle Ages, but was subsequently replaced with dh and later d. Its use has survived in Iceland and the Faroe Islands. The capital eth resembles a D with a line through the vertical stroke. The lower case resembles an insular d with a line through the top. The lower-case letter has been adopted to represent a voiced dental fricative in the IPA.
