ᛥ, named stan ("stone"), is a rare rune denoting st (the sound cluster ) in the expanded 32-type (*33-type) Anglo-Saxon Futhorc writing system (9th–12th c.). The glyph looks like a double-ended ᛗ (ᛗ+) or ᛖ (ᛖ+).
The rune is a so called "manuscript rune", as it is only recorded in manuscripts.
The character was added into unicode in 1999 with Unicode 3.0.
