Kana modifiers and marks
Multi-syllabic kana

I (い in hiragana or イ in katakana) is one of the Japanese kana each of which represents one mora. い is based on the sōsho style of the kanji character 以, and イ is from the radical (left part) of the kanji character 伊. In the modern Japanese system of sound order, it occupies the second position of the syllable chart, between あ and う. Additionally, it is the first letter in Iroha, before ろ. Both represent the sound [i]. In the Ainu language, katakana イ is written as y in their Latin-based syllable chart, and a small ィ after another katakana represents a diphthong.

Variant forms[edit]

Like other vowels, scaled-down versions of the kana (ぃ, ィ) are used to express sounds foreign to the Japanese language, such as フィ (fi). In some Okinawan writing systems, a small ぃ is also combined with the kana く (ku) and ふ to form the digraphs くぃ kwi and ふぃ hwi respectively, although the Ryukyu University system uses the kana ゐ/ヰ instead.

Origin[edit]

い comes from the left part of the Kanji 以, while イ originates from the left part of the Kanji 伊.[1] An alternate form - 𛀆, based on the full cursive form of 以 is one of the most common hentaigana, as it merged with い late in the development of modern Japanese writing.

  2. At the top right, a shorter stroke, slightly curving in the opposite direction.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
