Đ/đ/ð glyphs are often used ambiguously for two distinct characters:
1. The crossed D or dyet (Đ/đ) is a letter used in Vietnamese, some South Slavic (e.g. Croatian, Serbian), Moro and Sami languages, and also in linguistics as a phonetic symbol.
2. The eth (Ð/ð; also spelled edh or eð) is used in Icelandic, Faroese, and Old English.
