Thorn with stroke

Letter of the Latin alphabet

Ꝥ, or Þ (thorn) with stroke was a scribal abbreviation common in the Middle Ages. It was used for Old English: þæt, as well as Old Norse: þor-, the -þan/-ðan in síðan, 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, which caused the thorn with stroke abbreviation to be replaced with a thorn with a small t above the letter.
