A writing system is any conventional method of visually representing verbal communication. While both writing and spoken language are useful in conveying , writing differs in also being a reliable form of information storage and transfer. The processes of code writing systems involve shared understanding between writers and readers of the meaning behind the sets of characters that make up a script. Writing is usually recorded onto a durable medium, such as paper or electronic storage, although non-durable methods may also be used, such as writing on a computer display device, on a blackboard, in sand, or by skywriting.
The general attributes of writing systems can be placed into broad categories such as , syllabary, or logogram. Any particular system can have attributes of more than one category. In the alphabetic category, there is a standard set of letters (basic written or ) of and that encode based on the general principle that the letters (or letter pair/groups) represent phoneme. In a syllabary, each symbol correlates to a syllable or mora. In a logography, each character represents a word, morpheme, or other semantic units. Other categories include , which differ from alphabets in that vowels are not indicated, and or alphasyllabaries, with each character representing a consonant–vowel pairing. Alphabets typically use a set of 20-to-35 symbols to fully express a language, whereas syllabaries can have 80-to-100, and logographies can have several hundreds of symbols.
Most systems will typically have an ordering of its symbol elements so that groups of them can be coded into larger clusters like or (generally ), giving rise to many more possibilities () in meanings than the symbols can convey by themselves. Systems will also enable the concatenation of these smaller groupings (sometimes referred to by the generic term 'character strings') in order to enable a full expression of the language. The reading step can be accomplished purely in the mind as an internal process, or reading aloud. A special set of symbols known as punctuation is used to aid in structure and organization of many writing systems and can be used to help capture nuances and variations in the message's meaning that are communicated verbally by cues in rhythm, tone, pitch accent, inflection or intonation. A writing system will also typically have a method for formatting recorded messages that follows the spoken version's rules like its grammar and syntax so that the reader will have the meaning of the intended message accurately preserved.
Writing systems were preceded by proto-writing, which used , and other mnemonic symbols. Proto-writing lacked the ability to capture and express a full range of thoughts and ideas. The invention of writing systems, which dates back to the beginning of the Bronze Age in the late Neolithic Era of the late 4th millennium BC, enabled the accurate durable recording of human history in a manner that was not prone to the same types of error to which oral tradition is vulnerable. Soon after, writing provided postal system of long distance communication. With the advent of publishing, it provided the medium for an early form of mass communication.
The creation of a new alphabetic writing system for a language with an existing logographic writing system is called alphabetization, as when the People's Republic of China studied the prospect of alphabetizing the with Latin script, Cyrillic script, Arabic script, and even numbers, although the most common instance of it, converting to Latin script, is usually called romanization.
Writing systems are distinguished from other possible symbolic communication systems in that a writing system is always associated with at least one spoken language. In contrast, visual representations such as drawings, paintings, and non-verbal items on maps, such as contour lines, are not language-related. Some symbols on information signs, such as the symbols for male and female, are also not language related, but can grow to become part of language if they are often used in conjunction with other language elements. Some other symbols, such as Numeral system and the ampersand, are not directly linked to any specific language, but are often used in writing and thus must be considered part of writing systems.
Every human community possesses language, which many regard as an innate and defining condition of humanity. However, the development of writing systems, and the process by which they have supplanted traditional orality systems of communication, have been sporadic, uneven and slow. Once established, writing systems generally change more slowly than their spoken counterparts. Thus they often preserve features and expressions which are no longer current in the spoken language. One of the great benefits of writing systems is that they can preserve a permanent record of information expressed in a language.
All writing systems require:
An individual grapheme may be represented in a wide variety of ways, where each variation is visually distinct in some regard, but all are interpreted as representing the "same" grapheme. These individual variations are known as of a grapheme (compare with the term allophone used in linguistic study). For example, the minuscule letter a has different allographs when written as a cursive, capital letters, or typeface letter. The choice of a particular allograph may be influenced by the medium used, the writing instrument, the stylistic choice of the writer, the preceding and following graphemes in the text, the time available for writing, the intended audience, and the largely unconscious features of an individual's handwriting.
To represent a conceptual system, one uses one or more languages, e.g., mathematics is a conceptual system Metaphor and Analogy in the Sciences, p.126, Springer Science & Business Media (2013) and one may use first-order logic and a natural language together in representation.
The invention of the first writing systems is roughly contemporary with the beginning of the Bronze Age in the late Neolithic of the late 4th millennium BC. The Sumerian archaic cuneiform script and the Egyptian hieroglyphs are generally considered the earliest writing systems, both emerging out of their ancestral proto-literate symbol systems from 3400 to 3200 BC with earliest coherent texts from about 2600 BC. It is generally agreed that Sumerian writing was an independent invention; however, it is debated whether Egyptian writing was developed completely independently of Sumerian, or was a case of cultural diffusion.
A similar debate exists for the Chinese script, which developed around 1200 BC. Chinese script are probably an independent invention, because there is no evidence of contact between China and the literate civilizations of the Near East,David N. Keightley, Noel Barnard. The Origins of Chinese civilization. Page 415-416 and because of the distinct differences between the Mesopotamian and Chinese approaches to logogram and phonetic representation. Sex and Eroticism in Mesopotamian Literature. By Dr Gwendolyn Leick. Pg 3.
A hieroglyphic writing system used by pre-colonial Mi'kmaq, that was observed by missionaries from the 17th to 19th centuries, is thought to have developed independently. Although, there is some debate over whether or not this was a fully formed system or just a series of mnemonic pictographs.
It is thought that the first consonantal alphabetic writing appeared before 2000 BC, as a representation of language developed by Semitic people tribes in the Sinai-peninsula (see History of the alphabet). Most other alphabets in the world today either descended from this one innovation, many via the Phoenician alphabet, or were directly inspired by its design.
The first true alphabet is the Greek alphabet which consistently represents since 800 BC.
Several approaches have been taken to classify writing systems, the most common and basic one is a broad division into three categories: logographic, syllabic, and alphabetic (or segmental); however, all three may be found in any given writing system in varying proportions, often making it difficult to categorise a system uniquely. The term complex system is sometimes used to describe those where the admixture makes classification problematic. Modern linguists regard such approaches, including Diringer'sDavid Diringer (1962): Writing. London.

As each character represents a single word (or, more precisely, a morpheme), many logograms are required to write all the words of language. The vast array of logograms and the memorization of what they mean are major disadvantages of logographic systems over alphabetic systems. However, since the meaning is inherent to the symbol, the same logographic system can theoretically be used to represent different languages. In practice, the ability to communicate across languages only works for the closely related varieties of Chinese, as differences in syntax reduce the crosslinguistic portability of a given logographic system. Japanese uses kanji extensively in its writing systems, with most of the symbols carrying the same or similar meanings. However, the grammatical differences between Japanese and Chinese are significant enough that a long Chinese text is not readily understandable to a Japanese reader without any knowledge of basic Chinese grammar, though short and concise phrases such as those on signs and newspaper headlines are much easier to comprehend.
While most languages do not use wholly logographic writing systems, many languages use some logograms. A good example of modern western logograms are the Hindu-Arabic numerals: everyone who uses those symbols understands what 1 means whether he or she calls it one, eins, uno, yi, ichi, ehad, ena, or jedan. Other western logograms include the ampersand &, used for and, the at sign @, used in many contexts for at, the percent sign % and the many signs representing units of currency (dollar sign, ¢, Euro sign, Pound sign, ¥ and so on.)
Logograms are sometimes called , a word that refers to symbols which graphically represent abstract ideas, but linguists avoid this use, as Chinese characters are often semantics–phonetic compounds, symbols which include an element that represents the meaning and a phonetic complement element that represents the pronunciation. Some nonlinguists distinguish between lexigraphy and ideography, where symbols in lexigraphies represent words and symbols in ideographies represent words or morphemes.
The most important (and, to a degree, the only surviving) modern logographic writing system is the Chinese one, whose characters have been used with varying degrees of modification in varieties of Chinese, Japanese, Korean language, Vietnamese, and other east Asian languages. hieroglyphs and the Mayan writing system are also systems with certain logographic features, although they have marked phonetic features as well and are no longer in current use. Vietnamese speakers switched to the Latin alphabet in the 20th century and the Hanja is increasingly rare. The Japanese writing system includes several distinct forms of writing including logography.
As logographic writing systems use a single symbol for an entire word, a syllabary is a set of written symbols that represent (or approximate) , which make up . A symbol in a syllabary typically represents a consonant sound followed by a vowel sound, or just a vowel alone.
In a "true syllabary", there is no systematic graphic similarity between phonetically related characters (though some do have graphic similarity for the vowels). That is, the characters for , and have no similarity to indicate their common "k" sound (voiceless velar plosive). More recent creations such as the Cree syllabary embody a system of varying signs, which can best be seen when arranging the syllabogram set in an Syllable onset–Syllable coda or onset–Syllable rime table.
Syllabaries are best suited to languages with relatively simple syllable structure, such as Japanese. The English language, on the other hand, allows complex syllable structures, with a relatively large inventory of and complex consonant clusters, making it cumbersome to write English words with a syllabary. To write English using a syllabary, every possible syllable in English would have to have a separate symbol, and whereas the number of possible syllables in Japanese is around 100, in English there are approximately 15,000 to 16,000.
However, syllabaries with much larger inventories do exist. The Yi script, for example, contains 756 different symbols (or 1,164, if symbols with a particular tone diacritic are counted as separate syllables, as in Unicode). The Chinese script, when used to write Middle Chinese and the modern varieties of Chinese, also represents syllables, and includes separate glyphs for nearly all of the many thousands of syllables in Middle Chinese; however, because it primarily represents and includes different characters to represent homophonous morphemes with different meanings, it is normally considered a logographic script rather than a syllabary.
Other languages that use true syllabaries include Greek language (Linear B) and Indigenous languages of the Americas such as Cherokee. Several languages of the Ancient Near East used forms of cuneiform, which is a syllabary with some non-syllabic elements.
The first type of alphabet that was developed was the abjad. An abjad is an alphabetic writing system where there is one symbol per consonant. Abjads differ from other alphabets in that they have characters only for sounds. Vowels are not usually marked in abjads.
All known abjads (except maybe Tifinagh) belong to the Semitic family of scripts, and derive from the original Northern Linear Abjad. The reason for this is that Semitic languages and the related Berber languages have a morphemic structure which makes the denotation of redundant in most cases.
Some abjads, like Arabic and Hebrew, have markings for vowels as well. However, they use them only in special contexts, such as for teaching. Many scripts derived from abjads have been extended with vowel symbols to become full alphabets. Of these, the most famous example is the derivation of the Greek alphabet from the Phoenician abjad. This has mostly happened when the script was adapted to a non-Semitic language.
The term abjad takes its name from the old order of the Arabic alphabet's 'alif, bā', jīm, dāl, though the word may have earlier roots in Phoenician or Ugaritic. "Abjad" is still the word for alphabet in Arabic language, Malay and Indonesian.
abugida is an alphabetic writing system whose basic signs denote consonants with an inherent vowel and where consistent modifications of the basic sign indicate other following vowels than the inherent one.
Thus, in an abugida there may or may not be a sign for "k" with no vowel, but also one for "ka" (if "a" is the inherent vowel), and "ke" is written by modifying the "ka" sign in a way that is consistent with how one would modify "la" to get "le". In many abugidas the modification is the addition of a vowel sign, but other possibilities are imaginable (and used), such as rotation of the basic sign, addition of Diacritic and so on.
The contrast with "true syllabary" is that the latter have one distinct symbol per possible syllable, and the signs for each syllable have no systematic graphic similarity. The graphic similarity of most abugidas comes from the fact that they are derived from abjads, and the consonants make up the symbols with the inherent vowel and the new vowel symbols are markings added on to the base symbol.
In the Ge'ez script, for which the linguistic term abugida was named, the vowel modifications do not always appear systematic, although they originally were more so. Canadian Aboriginal syllabics can be considered abugidas, although they are rarely thought of in those terms. The largest single group of abugidas is the Brahmic family of scripts, however, which includes nearly all the scripts used in India and Southeast Asia.
The name abugida is derived from the first four characters of an order of the Ge'ez script used in some contexts. It was borrowed from Ethiopian languages as a linguistic term by Peter T. Daniels.
Many scholars, e.g. John DeFrancis, reject this class or at least labeling hangul as such. The Korean script is a conscious script creation by literate experts, which Daniels calls a "sophisticated grammatogeny". These include stenography and constructed scripts of hobbyists and fiction writers (such as Tengwar), many of which feature advanced graphic designs corresponding to phonologic properties. The basic unit of writing in these systems can map to anything from phonemes to words. It has been shown that even the Latin script has sub-character "features".See .
Some scripts, however, are truly ambiguous. The semi-syllabary of ancient Spain were syllabic for plosives such as p, t, k, but alphabetic for other consonants. In some versions, vowels were written redundantly after syllabic letters, conforming to an alphabetic orthography. Old Persian cuneiform was similar. Of 23 consonants (including null), seven were fully syllabic, thirteen were purely alphabetic, and for the other three, there was one letter for /C u/ and another for both /C a/ and /C i/. However, all vowels were written overtly regardless; as in the Brahmic abugidas, the /C a/ letter was used for a bare consonant.
The zhuyin phonetic glossing script for Chinese divides syllables in two or three, but into syllable onset, Syllable medial, and syllable rime rather than consonant and vowel. Pahawh Hmong is similar, but can be considered to divide syllables into either onset-rime or consonant-vowel (all consonant clusters and diphthongs are written with single letters); as the latter, it is equivalent to an abugida but with the roles of consonant and vowel reversed. Other scripts are intermediate between the categories of alphabet, abjad and abugida, so there may be disagreement on how they should be classified.
Cuneiform was probably the earliest non-linear writing. Its glyphs were formed by pressing the end of a reed stylus into moist clay, not by tracing lines in the clay with the stylus as had been done previously. The result was a radical transformation of the appearance of the script.
Braille is a non-linear adaptation of the Latin alphabet that completely abandoned the Latin forms. The letters are composed of raised bumps on the writing substrate, which can be leather (Louis Braille's original material), stiff paper, plastic or metal.
There are also transient non-linear adaptations of the Latin alphabet, including Morse code, the of various , and semaphore, in which Flag semaphore or Semaphore line are positioned at prescribed angles. However, if "writing" is defined as a potentially permanent means of recording information, then these systems do not qualify as writing at all, since the symbols disappear as soon as they are used. (Instead, these transient systems serve as signals.)
The Greek alphabet and its successors settled on a left-to-right pattern, from the top to the bottom of the page. Other scripts, such as Arabic alphabet and Hebrew language, came to be written right-to-left. Scripts that incorporate Chinese characters have traditionally been written vertically (top-to-bottom), from the right to the left of the page, but nowadays are frequently written left-to-right, top-to-bottom, due to Western culture influence, a growing need to accommodate terms in the Latin script, and technical limitations in popular electronic document formats. Chinese characters sometimes, as in signage, especially when signifying something old or traditional, may also be written from right to left. The Old Uyghur alphabet and its descendants are unique in being written top-to-bottom, left-to-right; this direction originated from an ancestral Semitic direction by rotating the page 90° counter-clockwise to conform to the appearance of vertical Chinese writing. Several scripts used in the Philippines and Indonesia, such as Hanunó'o, are traditionally written with lines moving away from the writer, from bottom to top, but are read horizontally left to right. While Ogham is written bottom to top and read vertically, commonly on the corner of a stone.
The direction of writing in the Semitic languages evolved throughout the years. Different findings show that in some past periods the Hebrew language was written from time to time from left to right and sometimes also one line left next line right and over again. This decision of writing from right to left is related in the physical way of writing the letters: in the ancient times, the writings were done on stone, thing that needed work with tools. since most people are right handed, it was more comfortable to "work" from right to left. when the writing developed into use of color on paper, which does not need physical power, the European systems that were developing also in that times, preferred to write from left to right and so to avoid "smearing" of the color and that in writing from left to right there is no hiding of the written sentence to the writer. That's the reason why most of the later script systems (Greek and its derivatives- Cyrillic script and Latin script) were written from left to right, while the Semitic scripts just preserved the writing from right to left.
A keyboard is the device most commonly used for writing via computer. Each key is associated with a standard code which the keyboard sends to the computer when it is pressed. By using a combination of alphabetic keys with such as Control key, Alt key, Shift key and AltGr key, various character codes are generated and sent to the CPU. The operating system intercepts and converts those signals to the appropriate characters based on the keyboard layout and input method, and then delivers those converted codes and characters to the running application software, which in turn looks up the appropriate glyph in the currently used font file, and requests the operating system to draw these on the Computer display.
