The character 手 (shǒu): hand

On a cream ground, a large open hand is drawn flat in coral orange, palm turned to the viewer, its five fingers spread and raised, with a few pale lines for the creases. Across the palm sits the character 手 in dark brown: a short oblique hooked onto the top of the stem, two bars crossing it of which the lower is much longer, and a stem that ends in a hook to the left.

Pronunciation: shǒu
Strokes: 4
Radical: 手

Where its shape comes from

A hand held up, fingers in the air and wrist at the bottom. On the bronze inscriptions the five fingers can still be counted one by one; the strokes that cut across today's character are what survives of them. Xu Shen files it among the pictures, the graphs that simply draw the thing they name.

A way to remember it

The upright shaft is the forearm, and the three bars crossing it are the fingers. The lowest of the three is the longest, and the first one, right at the top, runs on a slant instead of lying flat.

This is a memory aid, not the origin of the character.
