画 huà began as a hand holding a brush, drawing the boundaries of a field. The traditional form 畫 makes this vivid: at the top sits 聿 yù, the picture of a hand gripping a writing brush, and below it 田 tián, a field, framed by lines that mark out its edges. The original act was not art but demarcation: to take a brush and draw the limits of a plot of land, to delimit and bound. From "to draw a boundary line" the meaning broadened to drawing of every kind, then to the picture that results.

The simplified form 画 keeps the field 田 at its center and folds the brush and the bounding lines into the enclosing frame around it. The radical is 田 tián, the field whose edges were the first thing 画 ever drew. The 画 / 畫 pair is one glyph in two scripts: simplified 画 on the mainland and in Singapore, traditional 畫 in Taiwan, Hong Kong, and classical texts.

Three senses branch from the brush on the field:

1. To draw, to paint. The action of making a picture: 画画 huà huà (to draw, to paint), 画家 huàjiā (painter), 画图 huàtú (to draw a diagram).
2. A painting, a picture. The result of that action: 图画 túhuà (picture), 国画 guóhuà (Chinese painting), 漫画 mànhuà (comics, manga).
3. A stroke; to mark out. The single line of a written character, and by extension to delimit: 笔画 bǐhuà (the strokes of a character), 画线 huà xiàn (to draw a line).

The thread through all three is the brush laying down a line. Whether it bounds a field, shapes a landscape, or forms one stroke of a character, 画 is the deliberate mark a hand makes when it sets brush to surface.

The picture sense of 画 opens onto one of the oldest arts of the civilization. 国画 guóhuà, literally "national painting," is the name for traditional Chinese painting: ink and mineral colors on silk or paper, brushed rather than filled in, and sharing its tools and gestures with calligraphy. The same brush, the same ink, and the same trained wrist make both a character and a landscape, which is why the two arts are spoken of together as 书画 shūhuà (calligraphy and painting).

Set against 国画 is 油画 yóuhuà, "oil painting," the Western tradition that arrived later and is named for its medium rather than its nation. And at the popular end of the spectrum sits 漫画 mànhuà, the word that covers comics, cartoons, and the Japanese manga whose name is written with these very characters, read in Japanese as manga. One root, 画, reaches from the silk scroll in a museum to the comic page on a newsstand.

The third sense of 画 is the most concrete: a single stroke. 笔画 bǐhuà is the technical word for the strokes that make up a written character, the basic units of the writing system. To ask 这个字有几画 ("how many strokes does this character have") is to count its 画. Here the brush has narrowed all the way down to one line on the page.

This is where 画 huà brushes up against its near-twin 划 huà. The two share a sound and a root idea of a drawn line, and they overlap in some words, but they pull in different directions. 画 leans toward drawing and pictures: 画画, 画家, 笔画. 划 leans toward cutting, marking, and dividing a line through something: 划船 huá chuán (to row a boat, here read huá), 划分 huàfēn (to demarcate), 计划 jìhuà (a plan, a marked-out course). When you mean to depict or to picture, reach for 画; when you mean to slice, rule, or divide, reach for 划.

See the traditional form 畫 whole: a hand grips a brush, 聿, and below it lies a field, 田, with lines drawn around its edges. The first thing 画 ever did was bound a plot of land. Hold that brush over that field and watch the line it draws do three jobs in turn.

Let the line trace a scene and you have painting (画画, 国画, 漫画). Let it settle into one mark on the page and you have a single stroke of a character (笔画). Let it rule a border and you have delimiting, the sense that hands off to its twin 划 (划分). The radical 田 keeps the memory honest: every 画 is a hand setting brush to a surface and drawing a deliberate line.
