Distinguish from the letter eth (Ð, ð), which also represented /θ/ and /ð/ in Old English. Thorn was used at the beginning and end of words, while eth appeared in the middle. In modern Icelandic, thorn (þ) is still part of the alphabet.

❌The word 'then' was spelled with a thorn in Old English.' (when the sound is correct but the position is wrong)
