History of English, English written language

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 vowels 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 no more than about fifty to sixty, in English there are many thousands.

Other languages that use true syllabaries include Mycenaean Greek (Linear B) and Native American languages such as Cherokee. Several languages of the Ancient Near East used forms of cuneiform, which is a syllabary with some non-syllabic elements.

Segmental writing systems: Alphabets.

An alphabet is a small set of letters — basic written symbols — each of which roughly represents or represented historically a phoneme of a spoken language. The word alphabet is derived from alpha and beta, the first two symbols of the Greek alphabet.

In a perfectly phonemic alphabet, the phonemes and letters would correspond perfectly in two directions: a writer could predict the spelling of a word given its pronunciation, and a speaker could predict the pronunciation of a word given its spelling. Each language has general rules that govern the association between letters and phonemes, but, depending on the language, these rules may or may not be consistently followed.

Perfectly phonemic alphabets are very easy to use and learn and languages that have them (for example Serbocroatian or Finnish) have much lower barriers to literacy than languages such as English, which has a very complex and irregular spelling system. As languages often evolve independently of their writing systems, and writing systems have been borrowed for languages for which they were not designed, the degree to which letters of an alphabet correspond to phonemes of a language varies greatly from one language to another and even within a single language. In modern times, when linguists invent a writing system for a language that didn't previously have one, the goal is usually to develop a phonemic alphabet. It should be noted that a truly phonetic alphabet for a natural spoken language would be very cumbersome, as it would have to have a huge variety of phonetic variation. An example of such a writing system is the International Phonetic Alphabet (IPA).

Consonantal writing systems: Abjads.

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 consonantal sounds. Vowels are not usually marked in abjad.

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 vowels redundant in most cases.

Some abjads (such as Arabic and Hebrew) have markings for vowels as well, but 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, the most famous case being 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 consonants Alif, Bá, Jim, Dál, though the word may have earlier roots in Phoenician or Ugaritic.

Abjad is still the word for alphabet in Arabic, Malay and Indonesian.

Inherent-vowel writing systems: Abugidas.

An 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 diacritical marks and so on.

The contrast with "true syllabaries" 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.

Featural writing systems.

A featural script represents finer detail than an alphabet. Here symbols do not represent whole phonemes, but rather the elements (features) that make up the phonemes, such as voicing or its place of articulation. Theoretically, each feature could be written with a separate letter; and abjads or abugidas, or indeed syllabaries, could be featural, but the only prominent system of this sort is Korean hangul. In hangul, the featural symbols are combined into alphabetic letters, and these letters are in turn joined into syllabic blocks, so that the system combines three levels of phonological representation.

Many scholars, e.g. 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 stenographies and constructed scripts of hobbyists and fiction writers, many of which feature advanced graphic designs corresponding to phonologic properties. The basic unit of writing in these systems can map to anything from phones to words. It has been shown that even the roman script has sub-character “features”.

Ambiguous writing systems.

Most writing systems are not purely one type. The English writing system, for example, includes numerals and other logograms such as #, $, and &, and the phonemic letter clusters are a complex match to sound. As mentioned above, all logographic systems have phonetic components as well, whether that's along the lines of a syllabary, such as Chinese ("logo-syllabic"), or an abjad, as in Egyptian ("logo-consonantal").

Some scripts, however, are truly ambiguous. The semi-syllabaries 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 /Cu/ and another for both /Ca/ and /Ci/. However, all vowels were written overtly regardless; as in the Brahmic abugidas, the /Ca/ letter was used for a bare consonant.

The zhuyin phonetic glossing script for Chinese divides syllables in two or three, but into onset, medial, and 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.

Graphic classification of writing systems.

Perhaps the primary graphic distinction made in classifications is that of linearity. Linear writing systems are those in which the characters are composed of lines, such as the Latin alphabet and Chinese characters. Chinese characters are considered linear whether they're written with a ball-point pen or a calligraphic brush, or cast in bronze. Similarly, Egyptian hieroglyphs and Maya glyphs were often painted in linear outline form, but in formal situations they were carved in bas-relief. Non-linear systems, on the other hand, such as braille, are not composed of lines, no matter which instrument is used to write them. The earliest examples of writing are linear: the Sumerian script of c. 3300 BCE was linear, though its cuneiform descendants were not.

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 manual alphabets of various sign languages, and semaphore, in which flags or bars 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.

If the Edo script is indeed a complete writing system, it may be the only natural example of a script in which the color of the graphemes is contrastive.

Directionality.

Scripts are also graphically characterized by the direction in which they are written. Egyptian hieroglyphs were written in either horizontal direction, with the animal and human glyphs turned to face the beginning of the line. The early alphabet could be written in multiple directions, horizontally (left-to-right or right-to-left) or vertically (up or down). It was commonly written boustrophedonically: starting in one (horizontal) direction, then turning at the end of the line and reversing direction.

The Greek alphabet and its successors settled on a left-to-right pattern, from the top to the bottom of the page. In Timed Text (TT) Authoring Format, this pattern is abbreviated LRTB. Other scripts, such as Arabic and Hebrew, 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 influence, a growing need to accommodate terms in the Roman alphabet, and technical limitations in popular electronic document formats. The Uighur alphabet and its descendants are unique in being the only scripts 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.

Writing systems on computers.

Different ISO/IEC standards are defined to deal with each individual writing systems to implement them in computers. Today most of those standards are re-defined in a collective standard, the ISO/IEC 10646 "Universal Character Set", and a parallel, closely related work, The Unicode Standard. Both are generally encompassed by the term Unicode. In Unicode, each character, in every language's writing system, is (simplifying slightly) given a unique identification number, known as its code point. The computer's software uses the code point to look up the appropriate character in the font file, so the characters can be displayed on the page or screen.

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 modifier keys such as Ctrl, Alt, Shift and AltGr, 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 screen.

In computers and telecommunication systems, graphemes and other grapheme-like units that are required for text processing are represented by "characters" that typically manifest in encoded form. For technical aspects of computer support for various writing systems, see Universal Character Set, CJK (Chinese, Japanese, Korean) and Bi-directional text, as well as Category: Character encoding. 
 
 

Historical significance of writing systems.

Historians draw a distinction between prehistory and history, with history defined by the advent of writing. The cave paintings and petroglyphs of prehistoric peoples can be considered precursors of writing, but are not considered writing because they did not represent language directly.

Writing systems always develop and change based on the needs of the people who use them. Sometimes the shape, orientation and meaning of individual signs also changes over time. By tracing the development of a script it is possible to learn about the needs of the people who used the script as well as how it changed over time.
