References: Mostly from Richard Sears' Chinese Etymology site (authorisation), which in turn draws data from various collections of ancient forms of Chinese characters, including: Shuowen Jiezi (small seal), Jinwen Bian (bronze inscriptions), Liushutong (Liushutong characters) and Yinxu Jiaguwen Bian (oracle bone script).

Pictogram (象形) – a stylized hand, with bent wrist/forearm (hence the hook stroke at lower right). Earlier forms resemble 手 (shǒu), 寸 (cùn). The original meaning of the glyph was “elbow”, which is now written 肘 (OC *tkuʔ).

After the meaning “elbow” was forgotten, 九 was taken to symbolize a fist tightening to bump up against something; thus, there is a metaphorical bumping up of nine against ten, which is the last number when counting on one's fingers.

From Proto-Sino-Tibetan *d/s-kəw. Compare Tibetan དགུ (dgu).
