eth
n. countablen. the name for an old letter in English that looks like a 'd' with a line through it. It represents the 'th' sound in words like 'this' or 'that'.
n. a character used in Old English and modern Icelandic to represent the voiced dental fricative. It is typically written as 'ð' in lowercase and 'Ð' in uppercase.
The word 'then' would have used an eth in Old English.
Students of medieval literature must learn to distinguish between the letters eth and thorn when reading original manuscripts.
While the letter eth eventually disappeared from the English alphabet in favor of the 'th' digraph, it remains a functional part of the Icelandic orthographic system today.
The sound /ɛ/ followed by the sound of the letter, by analogy with other letter names, such as those of f, l, and m.
Refers to the grapheme itself; often paired with 'thorn' when discussing historical linguistics.
