A list of writing systems (or scripts), classified according to some common distinguishing features.

See Writing system for more information about the different kinds of writing systems. See also grapheme, a technical term used to refer to the individual base constituents of any given writing system.

The usual name of the script is given first (and bolded); the name of the language(s) in which the script is written follows (in brackets), particularly in the case where the language name differs from the script name. Other informative or qualifying annotations for the script may also be provided.

Pictographic/ideographic writing systems

Ideographic scripts (in which graphemes are ideograms representing concepts or ideas, rather than a specific word in a language), and pictographic scripts (in which the graphemes are iconic pictures) are not thought to be able to express all that can be communicated by language, as argued by the linguists John DeFrancis and J. Marshall Unger. Essentially, they postulate that no full writing system can be completely pictographic or ideographic; it must be able to refer directly to a language in order to faithfully represent that language. However, it is likely that they have not examined Blissymbols, hence the claim that Blissymbols may in fact be the exception.

Although a few pictographic or ideographic scripts exist today, there is no single way to read them, because there is no one-to-one correspondence between symbol and language. Hieroglyphs were commonly thought to be ideographic before they were translated, and to this day Chinese is often erroneously said to be ideographic. In some cases of ideographic scripts, only the author of a text can read it with any certainty, and it may be said that they are interpreted rather than read. Such scripts often work best as mnemonic aids for oral texts, or as outlines that will be fleshed out in speech.

Logographic writing systems

In logographic writing systems, glyphs represents words or morphemes (meaningful components of words, as in mean-ing-ful), rather than phonetic elements.

Note that no logographic script is comprised solely of logograms. All contain graphemes which represent phonetic (sound-based) elements as well. These phonetic elements may be used on their own (to represent, for example, grammatical inflections or foreign words), or may serve as phonetic complements to a logogram (used to specify the sound of a logogram which might otherwise represent more than one word). In the case of Chinese, the phonetic element is built into the logogram itself; in Egyptian and Mayan, many glyphs are purely phonetic, while others function as either logograms or phonetic elements, depending on context. For this reason, many such scripts may be more properly referred to as logosyllabic or complex scripts; the terminology used is largely a product of custom in the field, and is to an extent arbitrary.

Consonant-based logographies

Syllable-based logographies

Logographies based on Chinese

Syllabaries

In a syllabary, graphemes represent syllables or moras. (Note that the 19th century term syllabics usually referred to abugidas rather than true syllabaries.)

Part syllabic, part alphabetic scripts

In these systems, some consonant-vowel combinations are written as syllables, but others are written as consonant plus vowel. In the case of Old Persian, all vowels were written regardless, so it was effectively a true alphabet despite its syllabic component. In Japanese a similar system plays a minor role in foreign borrowings; for example, is written *," target="_blank" >and *+*.

Segmental scripts

A segmental script has graphemes which represent the phonemes (basic unit of sound) of a language.

Note that there need not be (and rarely is) a one-to-one correspondence between the graphemes of the script and the phonemes of a language. A phoneme may be represented only by some combination or string of graphemes, the same phoneme may be represented by more than one distinct grapheme, the same grapheme may stand for more than one phoneme, or some combination of all of the above.

Segmental scripts may be further divided according to the types of phonemes they typically record:

Abjads

An abjad is a segmental script containing symbols for consonants only, or where vowels are optionally written with diacritics ("pointing") or only written word-initially.

True alphabets

A true alphabet contains separate letters (not diacritic marks) for both consonants and vowels.
Linear nonfeatural alphabets
Linear alphabets are composed of lines on a surface, such as ink on paper.

Featural linear alphabets
A featural script has elements that indicate the components of articulation, such as bilabial consonants, fricatives, or back vowels. Scripts differ in how many features they indicate.

Manual alphabets
Manual alphabets are frequently found as parts of sign languages. The are not used for writing per se, but for spelling out words while signing.

Other non-linear alphabets
These are other alphabets composed of something other than lines on a surface.

Abugidas

An abugida, or alphasyllabary, is a segmental script in which vowel sounds are denoted by diacritical marks or other systematic modification of the consonants. Generally, however, if a single letter is understood to have an inherent unwritten vowel, and only vowels other than this are written, then the system is classified as an abugida regardless of whether the vowels look like diacritics or full letters. The vast majority of abugidas are found from India to Southeast Asia and belong historically to the Brāhmī family.

Abugidas of the Brāhmī family

Final consonant-diacritic abugidas
In at least one abugida, not only the vowel but any syllable-final consonant is written with a diacritic. That is, representing with an under-ring, and final * would written as .

Vowel-based abugidas
In a couple abugidas, the vowels are basic, and the consonants secondary. If no consonant is written in Pahawh Hmong, it is understood to be /k/; consonants are written after the vowel they precede in speech. In Japanese Braille, the vowels but not the consonants have independent status, and it is the vowels which are modified when the consonant is y or w.

Undeciphered systems thought to be writing

These writing systems have not been deciphered. In some cases, such as Meroitic, the sound values of the glyphs are known, but the texts still cannot be read because the language is not understood. In others, such as the Phaistos Disc, there is little hope of progress unless further texts are found. Several of these systems, such as Epi-Olmec and Indus, are claimed to have been deciphered, but these claims have not been confirmed by independent researchers. In Vinča and other cases the system, although symbolic, may turn out to not be writing.

Undeciphered manuscripts

A number of manuscripts from comparable recent past may be written in an invented writing system, a cipher of an existing writing system or may only be an hoax.
