Clerical script in the context of "Chinese character"

Chinese characters are logographs used to write the Chinese languages and others from regions historically influenced by Chinese culture. Of the four independently invented writing systems accepted by scholars, they represent the only one that has remained in continuous use. Over a documented history spanning more than three millennia, the function, style, and means of writing characters have changed greatly. Unlike letters in alphabets that reflect the sounds of speech, Chinese characters generally represent morphemes, the units of meaning in a language. Writing all of the frequently used vocabulary in a language requires roughly 2000–3000 characters; as of 2025, more than 100000 have been identified and included in The Unicode Standard. Characters are created according to several principles, where aspects of shape and pronunciation may be used to indicate the character's meaning.

The first attested characters are oracle bone inscriptions made during the 13th century BCE in what is now Anyang, Henan, as part of divinations conducted by the Shang dynasty royal house. Character forms were originally ideographic or pictographic in style, but evolved as writing spread across China. Numerous attempts have been made to reform the script, including the promotion of small seal script by the Qin dynasty (221–206 BCE). Clerical script, which had matured by the early Han dynasty (202 BCE – 220 CE), abstracted the forms of characters—obscuring their pictographic origins in favour of making them easier to write. Following the Han, regular script emerged as the result of cursive influence on clerical script, and has been the primary style used for characters since. Informed by a long tradition of lexicography, states using Chinese characters have standardized their forms—broadly, simplified characters are used to write Chinese in mainland China, Singapore, and Malaysia, while traditional characters are used in Taiwan, Hong Kong, and Macau.

The Chinese family of scripts includes writing systems used to write various East Asian languages, that ultimately descend from the oracle bone script invented in the Yellow River valley during the Shang dynasty. These include written Chinese itself, as well as adaptations of it for other languages, such as Japanese kanji, Korean hanja, Vietnamese chữ Hán and chữ Nôm, Zhuang sawndip, and Bai bowen. More divergent are the Tangut script, Khitan large script, Khitan small script and its offspring, the Jurchen script, as well as the Yi script, Sui script, and Geba syllabary, which were inspired by written Chinese but not descended directly from it. While written Chinese and many of its descendant scripts are logographic, others are phonetic, including the kana, Nüshu, and Lisu syllabaries, as well as the bopomofo semi-syllabary.

These scripts are written in various styles, principally seal script, clerical script, regular script, semi-cursive script, and cursive script. Adaptations range from the conservative, as in Korean, which used Chinese characters in their standard form with only a few local coinages, and relatively conservative Japanese, which has coined a few hundred new characters and used traditional character forms until the mid-20th century, to the extensive adaptations of Zhuang and Vietnamese, each coining over 10,000 new characters by Chinese formation principles, to the highly divergent Tangut script, which formed over 5,000 new characters by its own principles.

Strokes (simplified Chinese: 笔画; traditional Chinese: 筆畫; pinyin: bǐhuà) are the smallest structural units making up written Chinese characters. In the act of writing, a stroke is defined as a movement of a writing instrument on a writing material surface, or the trace left on the surface from a discrete application of the writing implement. The modern sense of discretized strokes first came into being with the clerical script during the Han dynasty. In the regular script that emerged during the Tang dynasty—the most recent major style, highly studied for its aesthetics in East Asian calligraphy—individual strokes are discrete and highly regularized. By contrast, the ancient seal script has line terminals within characters that are often unclear, making them non-trivial to count.

Study and classification of strokes is useful for understanding Chinese character calligraphy, ensuring character legibility, identifying fundamental components of radicals, and implementing support for the writing system on computers.

Cursive script (simplified Chinese: 草书; traditional Chinese: 草書; pinyin: cǎoshū; Japanese: 草書体, sōshotai; Korean: 초서, choseo; Vietnamese: thảo thư), often referred to as grass script, is a script style used in Chinese and East Asian calligraphy. It is an umbrella term for the cursive variants of the clerical script and the regular script.

The cursive script functions primarily as a kind of shorthand script or calligraphic style and is faster to write than other styles, but it can be difficult to read for those unfamiliar with it because of its abstraction and alteration of character structures. People who can read only standard or printed forms of Chinese or related scripts may have difficulty reading the cursive script.

Libian was a gradual, systematic simplification of Chinese character forms during the 2nd century BC, by which the Chinese writing system transitioned from the seal script character forms promulgated during the Qin dynasty (221–206 BC) to the clerical script characters associated with the Han dynasty (202 BC – 220 AD), through the process of making omissions, additions, or transmutations of the graphical form of a character to make it easier to write. Libian was one of two conversion processes towards the new clerical script character forms, with the other being liding, which involved the regularisation and linearisation of character shapes.

Wa is the oldest attested name of Japan and ethnonym of the Japanese people. From c. the 2nd century AD Chinese and Korean scribes used the Chinese character 倭; 'submissive'', ''distant'', ''dwarf' to refer to the various inhabitants of the Japanese archipelago, although it might have been just used to transcribe the phonetic value of a Japonic ethnonym with a respectively differing semantic connotation. In the 8th century, the Japanese started using the character 和, wa, 'harmony', 'peace', 'balance' instead due to the offensive nature of the former.
