Syllabaries

In the linguistic study of written languages, a syllabary is a set of written symbols that represent the syllables or (more frequently) moras which make up words.

A symbol in a syllabary, called a syllabogram, typically represents an (optional) consonant sound (simple onset) followed by a vowel sound (nucleus)—that is, a CV or V syllable—but other phonographic mappings, such as CVC, CV- tone, and C (normally nasals at the end of syllables), are also found in syllabaries.

Types

A writing system using a syllabary is ''complete'' when it covers all syllables in the corresponding spoken language without requiring complex orthographic / graphemic rules, like implicit codas ( ⇒ /C₁VC₂/) silent vowels ( ⇒ /C₁V₁C₂/) or echo vowels ( ⇒ /C₁V₁C₂/). This loosely corresponds to ''shallow'' orthographies in alphabetic writing systems.

''True'' syllabograms are those that encompass all parts of a syllable, i.e. initial onset, medial nucleus and final coda, but since onset and coda are optional in at least some languages, there are ''middle'' (nucleus), ''start'' (onset-nucleus), ''end'' (nucleus-coda) and ''full'' (onset-nucleus-coda) true syllabograms. Most syllabaries only feature one or two kinds of syllabograms and form other syllables by graphemic rules.

Syllabograms, hence syllabaries, are ''pure'', ''analytic'' or ''arbitrary'' if they do not share graphic similarities that correspond to phonic similarities, e.g. the symbol for ''ka'' does not resemble in any predictable way the symbol for ''ki'', nor the symbol for ''a''.
Otherwise they are ''synthetic'', if they vary by onset, rime, nucleus ''or'' coda, or ''systematic'', if they vary by all of them.
Some scholars, e.g. Daniels, reserve the general term for analytic syllabaries and invent other terms (abugida, abjad) as necessary. Some systems provide katakana language conversion.

Languages using syllabaries

Languages that use syllabic writing include Japanese, Cherokee, Vai, the Yi languages of eastern Asia, the English-based creole language Ndyuka, Xiangnan Tuhua, and the ancient language Mycenaean Greek ( Linear B). In addition, the undecoded Cretan Linear A is also believed by some to be a syllabic script, though this is not proven.

Chinese characters, the cuneiform script used for Sumerian, Akkadian and other languages, and the former Maya script are largely syllabic in nature, although based on logograms. They are therefore sometimes referred to as ''logosyllabic''.

The contemporary Japanese language uses two syllabaries together called kana (in addition to the non-syllabic systems kanji and romaji), namely hiragana and katakana, which were developed around 700. Because Japanese uses mainly CV (consonant + vowel) syllables, a syllabary is well suited to write the language. As in many syllabaries, vowel sequences and final consonants are written with separate glyphs, so that both ''atta'' and ''kaita'' are written with three kana: あった (''a-t-ta'') and かいた (''ka-i-ta''). It is therefore sometimes called a '' moraic'' writing system.

Languages that use syllabaries today tend to have simple phonotactics, with a predominance of monomoraic (CV) syllables. For example, the modern Yi script is used to write languages that have no diphthongs or syllable codas; unusually among syllabaries, there is a separate glyph for every consonant-vowel-tone combination (CVT) in the language (apart from one tone which is indicated with a diacritic).

Few syllabaries have glyphs for syllables that are not monomoraic, and those that once did have simplified over time to eliminate that complexity.
For example, the Vai syllabary originally had separate glyphs for syllables ending in a coda ''(doŋ),'' a long vowel ''(soo),'' or a diphthong ''(bai),'' though not enough glyphs to distinguish all CV combinations (some distinctions were ignored). The modern script has been expanded to cover all moras, but at the same time reduced to exclude all other syllables. Bimoraic syllables are now written with two letters, as in Japanese: diphthongs are written with the help of V or ''h''V glyphs, and the nasal coda is written with the glyph for ''ŋ'', which can form a syllable of its own in Vai.

In Linear B, which was used to transcribe Mycenaean Greek, a language with complex syllables, complex consonant onsets were either written with two glyphs or simplified to one, while codas were generally ignored, e.g. ''ko-no-so'' for '' Knōsos'', ''pe-ma'' for ''sperma.''

The Cherokee syllabary generally uses dummy vowels for coda consonants, but also has a segmental grapheme for /s/, which can be used both as a coda and in an initial /sC/ consonant cluster.

Difference from abugidas

The languages of India and Southeast Asia, as well as the Ethiopian Semitic languages, have a type of alphabet called an ''abugida'' or ''alphasyllabary''. In these scripts, unlike in pure syllabaries, syllables starting with the same consonant are generally expressed with graphemes based in a regular way on a common graphical elements. Usually each character representing a syllable consists of several elements which designate the individual sounds of that syllable.

In the 19th century these systems were called ''syllabics'', a term which has survived in the name of Canadian Aboriginal syllabics (also an abugida).

In a true syllabary there may be graphic similarity between characters that share a common consonant or vowel sound, but it is not systematic or at all regular. For example, the characters for 'ke', 'ka', and 'ko' in Japanese hiragana have no similarity to indicate their common "k" sound (these being: け, か and こ). Compare this with Devanagari, an abugida, where the characters for 'ke', 'ka' and 'ko' are के, का and को respectively, with क indicating their common "k" sound.

Comparison to alphabets

English, along with many other Indo-European languages like German and Russian, allows for complex syllable structures, making it cumbersome to write English words with a syllabary. A "pure" syllabary based on English would require a separate glyph for every possible syllable. Thus one would need separate symbols for "bag", "beg", "big", "bog", "bug", "bad", "bed", "bid", "bod", "bud", "bead", "bide", "bode", etc. Since English has well over 10,000 different possibilities for individual syllables, a syllabary would be poorly suited to represent the English language. However, such pure systems are rare. A workaround to this problem, common to several syllabaries around the world (including English loanwords in Japanese), is to write an echo vowel, as if the syllable coda were a second syllable: ''ba-gu'' for "bag", etc.
