Chữ NômChữ Nôm (, t͡ɕɨ˦ˀ˥ nom˧˧) is a logographic writing system formerly used to write the Vietnamese language. It uses Chinese characters (chữ Hán) to represent Sino-Vietnamese vocabulary and some native Vietnamese words, with other words represented by new characters created using a variety of methods, including phono-semantic compounds. This composite script was therefore highly complex and was accessible to less than five percent of the Vietnamese population who had mastered written Chinese.
Shuowen JieziShuowen Jiezi () is an ancient Chinese dictionary compiled by Xu Shen during the Eastern Han dynasty. Although not the first comprehensive Chinese character dictionary (the Erya predates it), it was the first to analyze the structure of the characters and to give the rationale behind them, as well as the first to use the principle of organization by sections with shared components called radicals (bùshǒu 部首, lit. "section headers"). Xu Shen, a Han Dynasty scholar of the Five Classics, compiled the Shuowen Jiezi.
Oracle bone scriptOracle bone script () is an ancient form of Chinese characters that were engraved on oracle bonesanimal bones or turtle plastrons used in pyromantic divination. Oracle bone script was used in the late 2nd millennium BC, and is the earliest known form of Chinese writing. The vast majority of oracle bone inscriptions, of which about 150,000 pieces have been discovered, were found at the Yinxu site located in Xiaotun Village, Anyang, Henan Province.
Japanese writing systemThe modern Japanese writing system uses a combination of logographic kanji, which are adopted Chinese characters, and syllabic kana. Kana itself consists of a pair of syllabaries: hiragana, used primarily for native or naturalised Japanese words and grammatical elements; and katakana, used primarily for foreign words and names, loanwords, onomatopoeia, scientific names, and sometimes for emphasis. Almost all written Japanese sentences contain a mixture of kanji and kana.
