Chinese is a group of languages spoken natively by the ethnic Han Chinese majority and many minority ethnic groups in China. Approximately 1.35 billion people, or 17% of the global population, speak a variety of Chinese as their first language.
In linguistics, a grapheme is the smallest functional unit of a writing system. The word grapheme is derived from Ancient Greek gráphō ('write'), and the suffix -eme by analogy with phoneme and other emic units. The study of graphemes is called graphemics. The concept of graphemes is abstract and similar to the notion in computing of a character. By comparison, a specific shape that represents any particular grapheme in a given typeface is called a glyph.
An ideogram or ideograph is a symbol that represents an idea or concept independent of any particular language. Some ideograms are more arbitrary than others: some are only meaningful assuming preexisting familiarity with some convention; others more directly resemble their signifieds. Ideograms that represent physical objects by visually resembling them are called pictograms.
Kana are syllabaries used to write Japanese phonological units, morae. In current usage, kana most commonly refers to hiragana and katakana. It can also refer to their ancestor magana, which were Chinese characters used phonetically to transcribe Japanese ; and hentaigana, which are historical variants of the now-standard hiragana.
An orthography is a set of conventions for writing a language, including norms of spelling, punctuation, word boundaries, capitalization, hyphenation, and emphasis.
Kanji are the logographic Chinese characters adapted from the Chinese script used in the writing of Japanese. They were made a major part of the Japanese writing system during the time of Old Japanese and are still used, along with the subsequently-derived syllabic scripts of hiragana and katakana. The characters have Japanese pronunciations; most have two, with one based on the Chinese sound. A few characters were invented in Japan by constructing character components derived from other Chinese characters. After the Meiji Restoration, Japan made its own efforts to simplify the characters, now known as shinjitai, by a process similar to China's simplification efforts, with the intention to increase literacy among the common folk. Since the 1920s, the Japanese government has published character lists periodically to help direct the education of its citizenry through the myriad Chinese characters that exist. There are nearly 3,000 kanji used in Japanese names and in common communication.
Egyptian hieroglyphs were the formal writing system used in Ancient Egypt for writing the Egyptian language. Hieroglyphs combined ideographic, logographic, syllabic and alphabetic elements, with more than 1,000 distinct characters. Cursive hieroglyphs were used for religious literature on papyrus and wood. The later hieratic and demotic Egyptian scripts were derived from hieroglyphic writing, as was the Proto-Sinaitic script that later evolved into the Phoenician alphabet. Egyptian hieroglyphs are the ultimate ancestor of the Phoenician alphabet, the first widely adopted phonetic writing system. Moreover, owing in large part to the Greek and Aramaic scripts that descended from Phoenician, the majority of the world's living writing systems are descendants of Egyptian hieroglyphs—most prominently the Latin and Cyrillic scripts through Greek, and the Arabic and Brahmic scripts through Aramaic.
A phonetic complement is a phonetic symbol used to disambiguate word characters (logograms) that have multiple readings, in mixed logographic-phonetic scripts such as Egyptian hieroglyphs, Akkadian cuneiform, Linear B, Japanese, and Mayan. Often they disambiguate an ideogram by spelling out the first or last syllable of the word; occasionally they may instead abbreviate an adjective that modifies the logogram.
Chinese characters are logographs used to write the Chinese languages and others from regions historically influenced by Chinese culture. Chinese characters have a documented history spanning over three millennia, representing one of the four independent inventions of writing accepted by scholars; of these, they comprise the only writing system continuously used since its invention. Over time, the function, style, and means of writing characters have evolved greatly. Unlike letters in alphabets that reflect the sounds of speech, Chinese characters generally represent morphemes, the units of meaning in a language. Writing a language's entire vocabulary requires thousands of different characters. Characters are created according to several different principles, where aspects of both shape and pronunciation may be used to indicate the character's meaning.
A phonemic orthography is an orthography in which the graphemes correspond consistently to the language's phonemes, or more generally to the language's diaphonemes. Natural languages rarely have perfectly phonemic orthographies; a high degree of grapheme–phoneme correspondence can be expected in orthographies based on alphabetic writing systems, but they differ in how complete this correspondence is. English orthography, for example, is alphabetic but highly nonphonemic.
The 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 naturalized 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. Because of this mixture of scripts, in addition to a large inventory of kanji characters, the Japanese writing system is considered to be one of the most complicated currently in use.
A word is a basic element of language that carries meaning, can be used on its own, and is uninterruptible. Despite the fact that language speakers often have an intuitive grasp of what a word is, there is no consensus among linguists on its definition and numerous attempts to find specific criteria of the concept remain controversial. Different standards have been proposed, depending on the theoretical background and descriptive context; these do not converge on a single definition. Some specific definitions of the term "word" are employed to convey its different meanings at different levels of description, for example based on phonological, grammatical or orthographic basis. Others suggest that the concept is simply a convention used in everyday situations.
Chinese characters are generally logographs, but can be further categorized based on the manner of their creation or derivation. Some characters may be analysed structurally as compounds created from smaller components, while some are not decomposable in this way. A small number of characters originate as pictographs and ideographs, but the vast majority are what are called phono-semantic compounds, which involve an element of pronunciation in their meaning.
A morphogram is the representation of a morpheme by a grapheme based solely on its meaning. Kanji is a writing system that makes use of morphograms, where Chinese characters were borrowed to represent native morphemes because of their meanings. Thus, a single character can represent a variety of morphemes which originally all had the same meaning. An example of this in Japanese would be the grapheme 東 [east], which can be read as higashi or azuma, in addition to its logographic representation of the morpheme tō. Additionally, in Japanese, the logographic (Chinese-derived) reading is called the on'yomi reading, and the morphographic reading is called the kun'yomi reading.
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.
Dyslexia is a complex, lifelong disorder involving difficulty in learning to read or interpret words, letters and other symbols. Dyslexia does not affect general intelligence, but is often co-diagnosed with ADHD. There are at least three sub-types of dyslexia that have been recognized by researchers: orthographic, or surface dyslexia, phonological dyslexia and mixed dyslexia where individuals exhibit symptoms of both orthographic and phonological dyslexia. Studies have shown that dyslexia is genetic and can be passed down through families, but it is important to note that, although a genetic disorder, there is no specific locus in the brain for reading and writing. The human brain does have language centers, but written language is a cultural artifact, and a very complex one requiring brain regions designed to recognize and interpret written symbols as representations of language in rapid synchronization. The complexity of the system and the lack of genetic predisposition for it is one possible explanation for the difficulty in acquiring and understanding written language.
A writing system comprises a set of symbols, called a script, as well as the rules by which the script represents a particular language. The earliest writing was invented during the late 4th millennium BC. Throughout history, each writing system invented without prior knowledge of writing gradually evolved from a system of proto-writing that included a small number of ideograms, which were not fully capable of encoding spoken language, and lacked the ability to express a broad range of ideas.
Hokkien, a variety of Chinese that forms part of the Southern Min family and is spoken in Southeastern China, Taiwan and Southeast Asia, does not have a unitary standardized writing system, in comparison with the well-developed written forms of Cantonese and Standard Chinese (Mandarin). In Taiwan, a standard for Written Hokkien has been developed by the Ministry of Education including its Dictionary of Frequently-Used Taiwan Minnan, but there are a wide variety of different methods of writing in Vernacular Hokkien. Nevertheless, vernacular works written in Hokkien are still commonly seen in literature, film, performing arts and music.
Heterogram is a term used mostly in the philology of Akkadian, and Pahlavi texts containing borrowings from Sumerian and Aramaic respectively. It refers to a special type of logogram or ideogram borrowed from another language to represent either a sound or meaning in the matrix language. It is now commonly accepted that they do not represent true borrowings from the embedded language and instead came to represent a separate register of orthographic archaisms.
