Kana

Kana is a compound of and , which eventually collapsed into kanna and ultimately kana. It was not until the 18th century that the early-nationalist movement, which promoted a move away from Sinocentric academia, began to reanalyze the script from a phonological point of view. In the following centuries, contrary to the traditional Sinocentric view, kana began to be considered a national Japanese writing system that was distinct from Chinese characters, which is the dominant view today. ==Terms==

Although the term 'kana' is now commonly understood as hiragana and katakana, it actually has broader application as listed below: • or : a syllabary. • or : phonetic kanji used as syllabary characters, historically used by men (who were more educated). • : the most prominent system of magana. • : cursive man'yōgana. • , , , or : a syllabary derived from simplified sōgana, historically used by women (who were less educated), historically sorted in Iroha order. • or : obsolete variants of hiragana. • or : a syllabary derived by using bits of characters in man'yōgana, historically sorted in gojūon order. • : hiragana and katakana, as opposed to kanji. • : magana for transcribing Japanese words, using, strict or loose, Chinese-derived readings (''on'yomi''). For example, would be spelt as , with two magana with on'yomi for ya and ma; likewise, spelt as for hi and to. • : magana for transcribing Japanese words, using native words ascribed to kanji (native "readings" or ''kun'yomi''). For example, would be spelt as , with three magana with kun'yomi for ya, ma and to; likewise, spelt as for natsu and kashi. • , , or : kanji used for meanings, historically used by men (who were more educated). • : mixed script including only kanji and katakana. == Hiragana and katakana ==

The following table reads, in gojūon order, as a, i, u, e, o (down first column), then ka, ki, ku, ke, ko (down second column), and so on. n appears on its own at the end. Asterisks mark unused combinations. • There are presently no kana for ye, yi or wu, as corresponding syllables do not occur natively in modern Japanese. • The (ye) sound is believed to have existed in pre-Classical Japanese, mostly before the advent of kana, and can be represented by the man'yōgana kanji 江. There was an archaic Hiragana () derived from the man'yōgana ye kanji 江, which is encoded into Unicode at code point U+1B001 (𛀁), but it is not widely supported. It is believed that e and ye first merged to ye before shifting back to e during the Edo period. If necessary, the modern orthography allows [je] (ye) to be written as いぇ (イェ), but this usage is limited and nonstandard. • The modern Katakana e, エ, derives from the man'yōgana 江, originally pronounced ye; • Some gojūon tables published during the 19th century list additional Katakana in the ye (), wu () and yi () positions. These are not presently used, and the latter two sounds never existed in Japanese. They were added to Unicode in version 14.0 in 2021. These sources also list (Unicode U+1B006, 𛀆) in the Hiragana yi position, and in the ye position. • Note that the き゚ゃ, き゚ゅ and き゚ょ, though they exist, are not used in standard Japanese orthography. • zi+y* and di+y* are often transcribed j* instead of zy* and dy*, according to contemporary pronunciation. The form jy* is also used in some cases. == Modern usage ==

The difference in usage between hiragana and katakana is stylistic. Usually, hiragana is the default syllabary, and katakana is used in certain special cases. Hiragana is used to write native Japanese words with no kanji representation (or whose kanji is thought obscure or difficult), as well as grammatical elements such as particles and inflections (okurigana). Today katakana is most commonly used to write words of foreign origin that do not have kanji representations, as well as foreign personal and place names. Katakana is also used to represent onomatopoeia and interjections, emphasis, technical and scientific terms, transcriptions of the Sino-Japanese readings of kanji, and some corporate branding. Kana can be written in small form above or next to lesser-known kanji in order to show pronunciation; this is called furigana. Furigana is used most widely in children's or learners' books. Literature for young children who do not yet know kanji may dispense with it altogether and instead use hiragana combined with spaces. Systems supporting only a limited set of characters, such as Wabun code for Morse code telegrams and single-byte digital character encodings such as JIS X 0201 or EBCDIK, likewise dispense with kanji, instead using only katakana. This is not necessary in systems supporting double-byte or variable-width encodings such as Shift JIS, EUC-JP, UTF-8 or UTF-16. == History ==

Old Japanese was written entirely in kanji, and a set of kanji called ''man'yōgana'' were first used to represent the phonetic values of grammatical particles and morphemes. As there was no consistent method of sound representation, a phoneme could be represented by multiple kanji, and even those kana's pronunciations differed in whether they were to be read as or , making decipherment problematic. The , a poetry anthology assembled sometime after 759 and the eponym of ''man'yōgana, exemplifies this phenomenon, where as many as almost twenty kanji were used for the mora ka. The consistency of the kana used was thus dependent on the style of the writer. Hiragana developed as a distinct script from cursive man'yōgana, whereas katakana developed from abbreviated parts of regular script man'yōgana as a glossing system to add readings or explanations to Buddhist sutras. Both of these systems were simplified to make writing easier. The shapes of many hiragana resembled the Chinese cursive script, as did those of many katakana the Korean gugyeol'', suggesting that the Japanese followed the continental pattern of their neighbors. Kana is traditionally said to have been invented by the Buddhist priest Kūkai in the ninth century. Kūkai certainly brought the Siddhaṃ script of India home on his return from China in 806; his interest in the sacred aspects of speech and writing led him to the conclusion that Japanese would be better represented by a phonetic alphabet than by the kanji which had been used up to that point. The modern arrangement of kana reflects that of the devanagari order used for Sanskrit in the Buddhist Siddhaṃ script hybrid known by the Japanese at the time, before, the traditional iroha arrangement used to follow the order of a poem which uses each kana once. Kana's vowel (a-i-u-e-o) and consonant (k, s, t, n, h, m, y, r, w) order coincide with the Sanskrit order, except for the letter s, but that is explained by the properties of Old Japanese and the version of Siddham buddhist monks learnt at the time. However, the first time this order was used in Japanese was during the Heian period by Myōkaku, a priest and Sanskrit scholar of the 12th century, member of the same order of Kūkai and credited as reviving Saskrit studies. In 1695, a priest named Keichū published a 5 volume book that is considered to be fundamental in fixing the sound order to this day; and this work, in turn, was probably based on an earlier 3 volume systematic study of the grammar and the writing system of the Buddhist Hybrid Sanskrit, written by another priest, Kakugen, in 1681, also member of the order of Kūkai and Myōkaku. However, hiragana and katakana did not quickly supplant ''man'yōgana. It was only in 1900 that the present set of kana was codified. All the other forms of hiragana and katakana developed before the 1900 codification are known as . Rules for their usage as per the spelling reforms of 1946, the , which abolished the kana for wi (ゐ・ヰ), we (ゑ・ヱ), and wo'' (を・ヲ) (except that the last was reserved as the accusative particle). ==Collation==

Kana are the basis for collation in Japanese. They are taken in the order given by the gojūon (あ い う え お ... わ を ん), though iroha (い ろ は に ほ へ と ... せ す (ん)) ordering is used for enumeration in some circumstances. Dictionaries differ in the sequence order for long/short vowel distinction, small tsu and diacritics. As Japanese does not use word spaces (except as a tool for children), there can be no word-by-word collation; all collation is kana-by-kana. == Disadvantages ==

The use of Chinese characters in Japanese to avoid homophones is not due to the scarcity of phonemes in the language—Hawaiian and Rotokas have even fewer phonemes than Japanese, yet they work fine with phonetic scripts. The fundamental reason lies in the fact that kana are not entirely phonetic: for instance, they do not indicate pitch accents (アクセント). Both "chopsticks" (箸) and "bridge" (橋) are written as "はし" (hashi). In Kana, "chopsticks" (箸) is pronounced as "はし" with a high-low pitch pattern (háshi), while "bridge" (橋) is pronounced as "はし" with a low-high pitch pattern (hashí). When speaking, the meaning must be distinguished by tone. Additionally, Japanese kana (except for "ん") do not include pure consonants, which makes it impossible to directly represent consonant clusters when transliterating foreign words. Instead, vowels must be inserted. For example, the English loanword 'club' is transliterated into Japanese as クラブ (kurabu). Similarly, the name of the U.S. President Donald Trump is rendered as ドナルド・トランプ (Donarudo Toranpu). == In Unicode ==

The hiragana range in Unicode is U+3040 ... U+309F, and the katakana range is U+30A0 ... U+30FF. The obsolete and rare characters (wi and we) also have their proper code points. Characters U+3095 and U+3096 are hiragana small ka and small ke, respectively. U+30F5 and U+30F6 are their katakana equivalents. Characters U+3099 and U+309A are combining dakuten and handakuten, which correspond to the spacing characters U+309B and U+309C. U+309D is the hiragana iteration mark, used to repeat a previous hiragana. U+309E is the voiced hiragana iteration mark, which stands in for the previous hiragana but with the consonant voiced (k becomes g, h becomes b, etc.). U+30FD and U+30FE are the katakana iteration marks. U+309F is a ligature of yori (より) sometimes used in vertical writing. U+30FF is a ligature of koto (コト), also found in vertical writing. Additionally, there are halfwidth equivalents to the standard fullwidth katakana. These are encoded within the Halfwidth and Fullwidth Forms block (U+FF00–U+FFEF), starting at U+FF65 and ending at U+FF9F (characters U+FF61–U+FF64 are halfwidth punctuation marks): There is also a small "Katakana Phonetic Extensions" range (U+31F0 ... U+31FF), which includes some additional small kana characters for writing the Ainu language. Further small kana characters are present in the "Small Kana Extension" block. Unicode also includes "Katakana letter archaic E" (U+1B000), as well as 255 archaic Hiragana, in the Kana Supplement block. It also includes a further 31 archaic Hiragana in the Kana Extended-A block. The Kana Extended-B block was added in September, 2021 with the release of version 14.0: == See also ==
