Hiragana is a Japanese syllabary, part of the Japanese writing system, along with katakana as well as kanji.

Katakana is a Japanese syllabary, one component of the Japanese writing system along with hiragana, kanji and in some cases the Latin script.

Kana are syllabaries used to write Japanese phonological units, morae. Such syllabaries include (1) the original kana, or magana, which were Chinese characters (kanji) used phonetically to transcribe Japanese, the most prominent magana system being man'yōgana (万葉仮名); the two descendants of man'yōgana, (2) hiragana, and (3) katakana. There are also hentaigana, which are historical variants of the now-standard hiragana. In current usage, 'kana' can simply mean hiragana and katakana.

<span class="mw-page-title-main">Iteration mark</span> Character or punctuation mark used to represent a duplicated character or word

Iteration marks are characters or punctuation marks that represent a duplicated character or word.

In the Japanese writing system, hentaigana are variant forms of hiragana.

Gyaru-moji or heta-moji is a style of obfuscated (cant) Japanese writing popular amongst urban Japanese youth. As the name gyaru-moji suggests, this writing system was created by and remains primarily employed by young women.

A is a Japanese kana that represents the mora consisting of single vowel. The hiragana character あ is based on the sōsho style of kanji 安, while the katakana ア is from the radical of kanji 阿. In the modern Japanese system of alphabetical order, it occupies the first position of the alphabet, before い. Additionally, it is the 36th letter in Iroha, after て, before さ. The Unicode for あ is U+3042, and the Unicode for ア is U+30A2.

<i>Chōonpu</i> Japanese punctuation mark

The chōonpu, also known as chōonkigō (長音記号), onbiki (音引き), bōbiki (棒引き), or Katakana-Hiragana Prolonged Sound Mark by the Unicode Consortium, is a Japanese symbol that indicates a chōon, or a long vowel of two morae in length. Its form is a horizontal or vertical line in the center of the text with the width of one kanji or kana character. It is written horizontally in horizontal text and vertically in vertical text. The chōonpu is usually used to indicate a long vowel sound in katakana writing, rarely in hiragana writing, and never in romanized Japanese. The chōonpu is a distinct mark from the dash, and in most Japanese typefaces it can easily be distinguished. In horizontal writing it is similar in appearance to, but should not be confused with, the kanji character 一 ("one").

In Japanese writing, the kana (hiragana) and (katakana) occupy the fourth place, between う and お, in the modern Gojūon (五十音) system of collating kana. In the Iroha, they occupy the 34th, between こ and て. In the table at right, え lies in the first column and the fourth row. Both represent.

In Japanese language, Ryakuji are colloquial simplifications of kanji.

Half-width kana are katakana characters displayed compressed at half their normal width, instead of the usual square (1:1) aspect ratio. For example, the usual (full-width) form of the katakana ka is カ while the half-width form is カ. Half-width hiragana is included in Unicode, and it is usable on Web or in e-books via CSS's font-feature-settings: "hwid" 1 with Adobe-Japan1-6 based OpenType fonts. Half-width kanji is usable on modern computers, and is used in some receipt printers, electric bulletin board and old computers.

Ma is one of the Japanese kana, which each represent one mora. The hiragana is made in three strokes, while the katakana in two. Both represent.

Wi is an obsolete Japanese kana, which is normally pronounced in current-day Japanese. The combination of a W-column kana letter with ゐ゙ in hiragana was introduced to represent in the 19th century and 20th century. It is presumed that 'ゐ' represented, and that 'ゐ' and 'い' represented distinct pronunciations before merging to sometime between the Kamakura and Taishō periods. Along with the kana for we, this kana was deemed obsolete in Japanese with the orthographic reforms of 1946, to be replaced by 'い/イ' in all contexts. It is now rare in everyday usage; in onomatopoeia and foreign words, the katakana form 'ウィ' (U-[small-i]) is used for the mora.

Kana Supplement is a Unicode block containing one archaic katakana character and 255 hentaigana characters. Additional hentaigana characters are encoded in the Kana Extended-A block.
