What 𝦢 means
𝦢 marks one rotation in SignWriting’s wall plane.
The wall plane is an upright plane parallel to the wall facing the signer. A rotation turns around an axis in that plane; “single” distinguishes this form from the double and alternating rotations.
By itself, 𝦢 does not name a signed word. In a complete SignWriting sign, it records movement alongside handshape, location, contact, face, and body symbols; their arrangement supplies the sign’s reading.
Where did this symbol come from?
It is one part of Sutton’s movement-writing system.
Valerie Sutton developed the wider movement-writing system in 1974. Its early history records a 1975–1980 shift from DanceWriting, an earlier way to record dance movement, toward SignWriting. SignWriting was designed to record signed forms and movement directly instead of translating them into spoken-language words.
Across signed languages, this symbol has a structural role, not one shared spoken-language translation.
Why does 𝦢 show as a box?
A box usually means the active font cannot draw this character.
Unicode gives 𝦢 an identity, but the font or renderer supplies its shape. Full SignWriting also needs a two-dimensional arrangement, so this character alone cannot display a complete sign.
Technical SignWriting component; by itself, it does not tell you the signed word.
A lone 𝦢 marks movement; it is not a complete signed word.

1Why does 𝦢 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
