U+1D9BB "𝦻" Signwriting Movement-Floorplane Hump Hitting Ceiling Small Triple Unicode Character
Unicode Version 17.0
𝦻
U+1D9BB "𝦻" Signwriting Movement-Floorplane Hump Hitting Ceiling Small Triple is a symbol from the SignWriting script, a writing system designed to visually represent the movements and positions of sign language. This specific glyph depicts a rapid, small-scale vertical motion, where a hand or other articulator moves upward along the floorplane (the horizontal plane in front of the signer), encounters a hump shaped curve, and then strikes an imaginary ceiling before bouncing back in a triple pulsation. It is used by linguists, educators, and Deaf communities to precisely notate the timing and spatial dynamics of signs that involve a quick, repeated up and down action within a confined vertical space.
