Thorn with stroke

(minuscule: ), or Þ (thorn) with stroke was a scribal abbreviation common in the Middle Ages. It was used for Old English "þæt" (Modern English "that"), as well as Old Norse "þor-", the "-þan"/"-ðan" in síðan,[1] "þat", "þæt", and "þess". In Old English texts, the stroke tended to be more slanted, while in Old Norse texts it was straight. In Middle English times, the ascender of the þ was reduced (making it similar to the Old English letter Wynn, ƿ), which caused the thorn with stroke abbreviation ( ) to be replaced with a thorn with a small t above the letter ( ).

Unicode encodes as U+A764 latin capital letter thorn with stroke (HTML Ꝥ), and at U+A765 latin small letter thorn with stroke (HTML ꝥ).

A thorn with a stroke on the descender also exists. The codepoints are U+A766 latin capital letter thorn with stroke through descender (HTML Ꝧ), and U+A767 latin small letter thorn with stroke through descender (HTML ꝧ).
