Awriting system (also called ascript) is a system of symbols used to representlanguage.[1][2] There are different kinds ofwriting systems, with symbols that represent different things. For example, English uses analphabet (theLatin alphabet).
Writing systems of the world today.
The fundamental principle is that symbols stand for sound, but there is more to it than that. The term "writing system" includes more than just (for example) an alphabet. Alphabets are part of a "graphic inventory" which includespunctuation,diacritics,ideograms (e.g. numbers) andlogograms (standing for specific words such as $, & etc.).
There are many different types of writing systems. Eachgrapheme, or symbol, can mean different things in different writing systems. Depending on what an individual symbol means, such as a whole word or a sound, each writing system is categorized as a different type.
Alphabets that only write consonants (and do not write vowels) are called abjads. The logic is that people in those areas know what vowels are used when the words are spoken. Many modern Abjads use optional diacritics to clarify their vowels, known as anImpure Abjad (less commonly,Voiced Abjad orAlphasyllabary). These are different from vowel letters in alphabets, as they are not written on their own but only as attached to a consonants.
Abugidas are alphabets where consonants are written as a symbol, and vowels are written asdiacritics. Diacritics in Abugidas are mandatory, as the lack of diacritic implies a default vowel sound (e.g. क (k) in Devanagari is pronounced 'ka' with no diacritic).
A syllabary is a writing system with symbols that each mean asyllable. This is different from Abugidas, as syllables with similar consonant or vowel sounds do not necessarily share similar symbols (e.g. か (ka) and き (ki) in Japanese).
A logography is a writing system with symbols that mean whole words or symbols that represent ideas. These symbols are called "logograms" or "logographs". In practice, no writing system is fully logographic: many symbols are combinations where one part represents the sound and another part represents the meaning. (e.g. 女 (nǚ), “woman”, and 马 (mǎ), “horse”, create 妈 (mā) "mother" in Mandarin Chinese).
Each writing system can be written in different directions. English (which uses the Latin alphabet) is written from left to right. Some languages, likeArabic, are written from right to left.
Some languages can be written vertically, such asChinese and Japanese (from top to bottom), andHanuoo (from bottom to top).
Besides being written horizontally and vertically, languages could theoretically be written diagonally, but no known examples of this exist.
