Stroke (CJK character)


CJKV strokes are the calligraphic strokes needed to write the Chinese characters in regular script used in East Asia. CJK strokes are the classified set of line patterns that may be arranged and combined to form Chinese characters (also known as Hanzi) in use in China, Japan, Korea, and to a lesser extent in Vietnam (see CJK characters).

The study and classification of CJK strokes aid in:

When writing Han radicals, a single stroke includes all the motions necessary to produce a given part of a character before lifting the writing instrument from the writing surface; thus, a single stroke may have abrupt changes in direction within the line. For example:

CJK strokes are an attempt to identify and classify all single-stroke components that can be used to write Han radicals. There are some thirty distinct types of strokes recognized in Chinese characters, some of which are compound strokes made from basic strokes. The compound strokes comprise more than one movement of the writing instrument, and many of these have no agreed-upon name.

A basic stroke is a single calligraphic mark moving in one direction across a writing surface. The following table lists a selection of basic strokes divided into two stroke groups: simple and combining. "Simple strokes" (such as Héng "Horizontal" and Diǎn "Dot") can be written alone. "Combining strokes" (such as Zhé "Break" and Gōu "Hook") never occur alone, but must be paired with at least one other stroke forming a compound stroke. Thus, they are not in themselves individual strokes.

Note, the basic stroke Diǎn "Dot" is rarely a real dot. Instead it usually takes the shape of a very small line pointing in one of several directions, and may be long enough to be confused with other strokes.

A compound stroke (also called a complex stroke) is produced when two or more basic strokes are combined in a single stroke written without lifting the writing instrument from the writing surface. The character 永 (pinyin: yǒng) "eternity" described in more detail below demonstrates one of these compound strokes. The centre line is a compound stroke that combines three stroke shapes in a single stroke.

In most cases, concatenating basic strokes together form a compound stroke. For example, Shù combined with Gōu produce SG-black.png (Shù Gōu). A stroke naming convention sums the names of the basic strokes, in the writing order.
