Ꝥ (minuscule: ꝥ), 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, "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 Ꝥ as U+A764 Ꝥ latin capital letter thorn with stroke (HTML: Ꝥ), and ꝥ at U+A765 ꝥ latin small letter thorn with stroke (HTML: ꝥ).
A thorn with a stroke on the descender also exists. The codepoints are U+A766 Ꝧ latin capital letter thorn with stroke through descender (HTML: Ꝧ), and U+A767 ꝧ latin small letter thorn with stroke through descender (HTML: ꝧ).
Famous quotes containing the words thorn and/or stroke:
“So long as I have been here I have not willingly planted a thorn in any man’s bosom.”
—Abraham Lincoln (1809–1865)
“All I have to do
is hear his name
and every hair on my body
just bristles with desire.
When I see
the moon of his face,
this frame of mine
oozes sweat like a moonstone.
When that man
as dear to me as breath
steps close enough to me
to stroke my neck,
the thought of jealousy
is shattered in my heart
that’s hard as diamond
sometimes.”
—Amaru (c. seventh century A.D.)
