H.G. Wells argued that writing has the ability to "put agreements, laws, commandments on record. It made the growth of states larger than the old city states possible. It made a continuous historical consciousness possible. The command of the priest or king and his seal could go far beyond his sight and voice and could survive his death".[2]
Writing systems
Main article: Writing system
The major writing systems – methods of inscription – broadly fall into four categories: logographic, syllabic, alphabetic, and featural. Another category, ideographic (symbols for ideas), has never been developed sufficiently to represent language. A sixth category, pictographic, is insufficient to represent language on its own, but often forms the core of logographies.
Logographies
A logogram is a written character which represents a word or morpheme. The vast number of logograms needed to write a language, and the many years of Chinese characters, cuneiform, and Mayan, where a glyph may stand for a morpheme, a syllable, or both; "logoconsonantal" in the case of hieroglyphs), and many have an ideographic component (Chinese "radicals", hieroglyphic "determiners"). For example, in Mayan, the glyph for "fin", pronounced "ka'", was also used to represent the syllable "ka" whenever the pronunciation of a logogram needed to be indicated, or when there was no logogram. In Chinese, about 90% of characters are compounds of a semantic (meaning) element called a radical with an existing character to indicate the pronunciation, called a phonetic. However, such phonetic elements complement the logographic elements, rather than vice versa.
The main logographic system in use today is Chinese characters, used with some modification for various languages of China, and Japanese. Korean, even in South Korea, today uses mainly the phonetic Hangul system.
Syllabaries
A syllabary is a set of written symbols that represent (or approximate) syllables. A glyph in a syllabary typically represents a consonant followed by a vowel, or just a vowel alone, though in some scripts more complex syllables (such as consonant-vowel-consonant, or consonant-consonant-vowel) may have dedicated glyphs. Phonetically related syllables are not so indicated in the script. For instance, the syllable "ka" may look nothing like the syllable "ki", nor will syllables with the same vowels be similar.
Syllabaries are best suited to languages with relatively simple syllable structure, such as Japanese. Other languages that use syllabic writing include the Linear B script for Mycenaean Greek; Cherokee; Ndjuka, an English-based creole language of Surinam; and the Vai script of Liberia. Most logographic systems have a strong syllabic component. Ethiopic, though technically an alphabet, has fused consonants and vowels together to the point that it's learned as if it were a syllabary.
Alphabets
See also: History of the alphabet
An alphabet is a set of symbols, each of which represents or historically represented a phoneme of the language. In a perfectly phonological 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.
As languages often evolve independently of their writing systems, and writing systems have been borrowed for languages they were not designed for, 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.
Abjads
In most of the writing systems of the Middle East, it is usually only the consonants of a word that are written, although vowels may be indicated by the addition of various diacritical marks. Writing systems based primarily on marking the consonant phonemes alone date back to the hieroglyphics of ancient Egypt. Such systems are called abjads, derived from the Arabic word for "alphabet".
Abugidas
In most of the alphabets of India and Southeast Asia, vowels are indicated through diacritics or modification of the shape of the consonant. These are called abugidas. Some abugidas, such as Ethiopic and Cree, are learned by children as syllabaries, and so are often called "syllabics". However, unlike true syllabaries, there is not an independent glyph for each syllable.
Sometimes the term "alphabet" is restricted to systems with separate letters for consonants and vowels, such as the Latin alphabet, although abugidas and abjads may also be accepted as alphabets. Because of this use, Greek is often considered to be the first alphabet.
Featural scripts
A featural script notates the building blocks of the phonemes that make up a language. For instance, all sounds pronounced with the lips ("labial" sounds) may have some element in common. In the Latin alphabet, this is accidentally the case with the letters "b" and "p"; however, labial "m" is completely dissimilar, and the similar-looking "q" and "d" are not labial. In Korean hangul, however, all four labial consonants are based on the same basic element. However, in practice, Korean is learned by children as an ordinary alphabet, and the featural elements tend to pass unnoticed.
Another featural script is SignWriting, the most popular writing system for many sign languages, where the shapes and movements of the hands and face are represented iconically. Featural scripts are also common in fictional or invented systems, such as Tolkien's Tengwar.
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 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.
Tools and materials
See also: writing implements
The many tools and writing materials used throughout history include stone tablets, clay tablets, bamboo slats, wax tablets, vellum, parchment, paper, copperplate, styluses, quills, ink brushes, pencils, pens, and many styles of lithography. It is speculated that the Incas might have employed knotted cords known as quipu (or khipu) as a writing system.[3]
The typewriter and various forms of word processors have subsequently become widespread writing tools, and various studies have compared the ways in which writers have framed the experience of writing with such tools as compared with the pen or pencil.
