What 𡶊 means
An old spelling of 陀: uneven or sloping ground.
Dictionaries record 𡶊 as a written variant of 陀 (tuó), whose old senses cover uneven, sloping or dangerous ground — the terrain behind compounds like 陂陀, 'uneven ground'. Taiwan's Ministry of Education variant-character dictionary cites this exact shape in 四聲篇海, a centuries-old Chinese character dictionary, and traces the 陀 family back to an inscription on a Warring States bronze vessel — that last piece of evidence belongs to 陀's history, not to this exact glyph.
The shape tells the same story. Writers could swap the 'hill' component 阜 for 'mountain' 山 — both picture landforms — while the lower part wavered between 它 and 㐌, two shapes easy to confuse in writing. Variants like this usually began as look-alike swaps that stuck; dictionaries later sorted them into families under their standard form.
Would anyone write 𡶊 today?
Rarely, if ever — modern texts write 陀; 𡶊 lives in dictionaries.
It is a recorded variant spelling — the kind dictionaries keep on record so old books can be read and transcribed faithfully — rather than a character you'd use in new writing. You might meet it in a digitized classic, a variant table or a Unicode chart — or as an empty box where a font fails to cover it.
Its parent 陀 does better: it lives on in the everyday word 陀螺, 'spinning top', in transliterations like 佛陀, 'Buddha', and in the name of Mount Putuo (普陀), the island-mountain sacred to Guanyin, the bodhisattva of compassion — read tuó there too.

Questions people ask
2Is 𡶊 the same character as 陀?
In dictionary terms, yes — 𡶊 is a recorded written variant of 陀, sharing its reading tuó and senses, though each has its own code point. For anything written today, use the standard form 陀.
Why does 𡶊 show as a box or blank space?
It sits in Unicode's Extension B, a block many fonts do not cover. When the active font lacks the glyph, apps draw a box — the character in the text is still correct.
