Gojūon

In the Japanese language, the is a traditional system ordering kana characters by their component phonemes, roughly analogous to alphabetical order. The "fifty" (''gojū'') in its name refers to the 5×10 grid in which the characters are displayed. Each kana, which may be a hiragana or katakana character, corresponds to one sound in Japanese. As depicted at the right using hiragana characters, the sequence begins with あ (''a''), い (''i''), う (''u''), え (''e''), お (''o''), then continues with か (''ka''), き (''ki''), く (''ku''), け (''ke''), こ (''ko''), and so on and so forth for a total of ten rows of five columns.

Although nominally containing 50 characters, the grid is not completely filled, and, further, there is an extra character added outside the grid at the end: with 5 gaps and 1 extra character, the current number of distinct kana in a syllabic chart in modern Japanese is therefore 46. Some of these gaps have always existed as gaps in sound: there was no ''yi'' or ''wu'' even in Old Japanese, with the kana for ''i'' and ''u'' doubling up for those phantom values. ''Ye'' persisted long enough for kana to be developed for it, but disappeared in Early Middle Japanese, having merged with ''e''. Much later, with the spelling reforms after World War II, the kana for ''wi'' and ''we'' were replaced with ''i'' and ''e'', the sounds they had merged with. The kana for syllabic ''n'' (hiragana ん) is not part of the grid, as it was introduced long after the ''gojūon'' ordering was devised. (Previously ''mu'' (hiragana む) was used for this sound.)

The ''gojūon'' contains all the basic kana, but it does not include:
*versions of kana with a ''dakuten'' such as が (''ga'') or だ (''da''), or kana with '' handakuten'' such as ぱ (''pa'') or ぷ (''pu''),
*smaller kana (sutegana), such as the ''sokuon'' (っ) or in the ''yōon'' (ゃ,ゅ,ょ).

The ''gojūon'' order is the prevalent system for collating Japanese in Japan. For example, dictionaries are ordered using this method.
Other systems used are the ''iroha'' ordering, and, for kanji, the radical ordering.

History

The ''gojūon'' arrangement is thought to have been influenced by both the Siddham script used for writing Sanskrit and the Chinese ''fanqie'' system.

The monk Kūkai introduced the Siddhaṃ script to Japan in 806 on his return from China. Belonging to the Brahmic family of scripts, the Sanskrit ordering of letters was used for it. Buddhist monks who invented katakana chose to use the word order of Sanskrit and Siddham, since important Buddhist writings were written with those alphabets.

In an unusual set of events, although it uses Sanskrit organization (grid, with order of consonants and vowels), it also uses the Chinese order of writing (in columns, right-to-left).

The order of consonants and vowels, and the grid layout, originates in Sanskrit ''shiksha'' (''śikṣā'', Hindu phonetics and phonology), and Brāhmī script, as reflected throughout the Brahmic family of scripts. Specifically, the consonants are ordered from the back to the front of the mouth (velar to labial).

The Sanskrit was written left-to-right, with vowels changing in rows, not columns; writing the grid vertically follows Chinese writing convention.

Discrepancies

There are three ways in which the grid does not exactly accord with Sanskrit ordering of Modern Japanese; that is because the grid is based on Old Japanese, and some sounds have changed in the interim.

''s''/

What is now ''s''/ was previously pronounced either or , hence its location corresponding to Sanskrit ; in Sanskrit appears towards the end of the list.Miller, Roy Andrew ''The Japanese Language,'' , p. 128:
"The Indic order of listing phonemes as found in the arrangement of this so-called 'siddhāṃ' script, as well as in all the Indic writing systems, arranges the consonants in the following order: k, kh, g, gh, ñ, c, ch, j, jh, ṭ, ṭh, ḍ, ḍh, ṇ, t, th, d, dh, p, ph, b, bh, m, y, r, l, v, ś, ṣ, s, and ḥ ... Here the juxtaposition of modern 'h', Old Japanese 'f', with Indic 'p' is interesting and significant; the only other point which needs particular comment is the location of modern Japanese 's' following 'k'. This is easily understood since modern Japanese 's' goes back to the Old Japanese affricate phoneme which had an allophone before Old Japanese and an allophone before ."

''h''/

Kana starting with ''h'' (e.g. ), ''b'' (e.g. ) and ''p'' (e.g. ) are placed where ''p/b'' are in Sanskrit (in Sanskrit, ''h'' is at the end) and the diacritics do not follow the usual pattern: ''p/b'' (as in Sanskrit) is the usual unvoiced/voiced pattern, and has different articulation. This is because was previously , and pronouncing as is recent.

(More detail at Old Japanese: Consonants; in brief: prior to Old Japanese, modern was presumably , as in Ryukyuan languages. Proto-Japanese is believed to have split into Old Japanese and the Ryukyuan languages in the Yamato period (250–710). In Old Japanese (from 9th century) and on to the 17th century, was pronounced . The earliest evidence was from 842, by the monk Ennin, writing in the '' Zaitōki'' that Sanskrit is more labial than Japanese. The Portuguese later transcribed the は-row as ''fa/fi/fu/fe/fo''.)

''n''/

Syllable-final ''n'' () was not present in Old Japanese (it developed following Chinese borrowings), does not fit with other characters due to having no vowel, and thus is attached at the end of the grid, as in Sanskrit treatment of miscellaneous characters.

Examples

The earliest example of a ''gojūon''-style layout dates from a manuscript known as dated –1028. In contrast, the earliest example of the alternative iroha ordering is from the 1079 text .

''Gojūon'' ordering was first used for a dictionary in the 1484 ; following this use, ''gojūon'' and ''iroha'' were both used for a time, but today ''gojūon'' is more prevalent.

Today the ''gojūon'' system forms the basis of input methods for Japanese mobile phones – each key corresponds to a column in the ''gojūon'', while the number of presses determines the row. For example, the '2' button corresponds to the ''ka''-column (''ka'', ''ki'', ''ku'', ''ke'', ''ko''), and the button is pressed repeatedly to get the intended kana.

Table

This table uses the vertical system of Japanese writing, and should be read from the top down, starting from the rightmost column, then to the left. In each entry, the top entry is the hiragana, the second entry is the corresponding katakana, the third entry is the Hepburn romanization of the kana, and the fourth entry is the pronunciation written in the International Phonetic Alphabet (IPA). Please see Japanese phonology for more details on the individual sounds.

#^ These kana are no longer in common use. Wi and we kana were included in the 1900 standard for kana but removed by subsequent orthographic reforms. Kana for writing explicit yi, ye and wu sounds were given by some nineteenth century textbooks but were not included in the 1900 standard. Since ''e'' and ''ye'' existed as different phonemes in historic Japanese literature (having since merged), some specialised scholarly works use え/𛀀 (from the man'yōgana character 衣) to transcribe ''e'' and 𛀁/エ (from man'yōgana 江, where エ is the modern Katakana ''e'') to transcribe ''ye''. These five are normally replaced with the plain vowel kana () in the charts that Japanese use, but that has not been done here to avoid confusion.

The rows are referred to as , and the columns as . They are named for their first entry, thus the rows are (top to bottom) while the columns are (right to left) . These are sometimes written in katakana, such as , and conspicuously used when referring to Japanese verb conjugation – for example, the verb is of type.

Ordering of variant kana

In the ordering based on the ''gojūon'', smaller versions of kana are treated in the same way as full-size versions:
* The ''sokuon'', the small kana ''tsu'', is ordered at the same position as the large ''tsu''. When the words are otherwise identical, it goes ''after'' them. For example,
*: まつ,　まったく,　まつば,　まとう　(''matsu'', ''mattaku'', ''matsuba'', ''matou'')
* ''Yōon'' sounds are ordered in the same positions as the full-sized sounds. When the words are otherwise identical, they collate ''after'' them. For example,
*: きや,　きゃ,　きやく,　きゃく,　きゆ　(''kiya'', ''kya'', ''kiyaku'', ''kyaku'', ''kiyu'').

Voiced versions (those with a ''dakuten'') are classified under their unvoiced versions; If the words are otherwise identical, the voiced version is placed ''after'' the unvoiced; '' handakuten'' are placed after dakuten. For example,
: すす,　すず,　すすき,　すすぎ,　すずき,　すすむ,　すずむ　(''susu'', ''suzu'', ''susuki'', ''susugi'', ''suzuki'', ''susumu'', ''suzumu'').
and
: は,　ば,　ぱ　(''ha'', ''ba'', ''pa'')

Mnemonics

To remember the ''gojūon'', various mnemonics have been devised. For example,
:''Ah, Kana Symbols: Take Note How Many You Read Well.''

The first letters in such phrases give the ordering of the non-voiced initial sounds.

For vowel ordering, the vowel sounds in the following English phrase may be used as a mnemonic:
:''Ah, we soon get old.''
The vowel sounds in the English words approximate the Japanese vowels: a, i, u, e, o.
