Thorn, or þorn (Þ, þ), is a letter in the Anglo-Saxon and Icelandic alphabets. It was also used in medieval Scandinavia, but was later replaced with the digraph “th”.
The modern Digraph th began to grow in popularity during the 14th century; at the same time, the shape of thorn grew less distinctive, with the letter losing its ascender (becoming similar in appearance to the old wynn, which had fallen out of use by 1300) and, in some hands, such as that of the scribe of the unique mid-15th century manuscript of The Boke of Margery Kempe, ultimately becoming indistinguishable from the letter Y.
