List of writing systems
Writing systems are used to record human language, and may be classified according to certain common features.
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 true writing system can be completely pictographic or ideographic; it must be able to refer directly to a language in order to have the full expressive capacity of a language. Unger disputes claims made on behalf of Blissymbols in his 2004 book Ideogram.
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.
There are also symbol systems used to represent things other than language:
In logographic writing systems, glyphs represent words or morphemes (meaningful components of words, as in mean-ing-ful) rather than phonetic elements.
No logographic script is composed solely of logograms; all contain graphemes that 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 that 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, whereas 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.
In a syllabary, graphemes represent syllables or moras. (The 19th-century term syllabics usually referred to abugidas rather than true syllabaries.)
In most of 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, [tu] is written [to]+[u], and [ti] as [te]+[i]. Paleohispanic semi-syllabaries behaved as a syllabary for the stop consonants and as an alphabet for the rest of consonants and vowels.
