The dotted i (І і; italics: ''І і ''), also called decimal i, is a letter of the Cyrillic script. It commonly represents the close front unrounded vowel , like the pronunciation of ⟨i⟩ in "machine". It is used in the orthographies of the Belarusian, Kazakh, Khakas, Komi, Rusyn and Ukrainian languages, where it is the equivalent of the Cyrillic letter i (И и) as used in Russian and other languages. (Ukrainian і is therefore Russian и, while Ukrainian uses и for a sound close to Russian ы. Belarusian meanwhile uses only і and ы, excluding и entirely. Rusyn uses і, и, and ы for three different sounds: /i/, /ɪ/, and /ɨ/ respectively.) In Komi, і occurs only after the consonants д, з, л, н, с, and т and does not palatalize them, whereas и does. In Kazakh and Khakas, і represents /ɪ/, as in "bit". Just like the Latin letters I/i (and J/j), the dot above the letter only appears in its lowercase form, and only if that letter is not combined with a diacritic above it (notably the diaeresis used in Ukrainian to note the letter ''yi'' of its alphabet, and the macron). But even in that case (and as with the Latin letters i and j), this dot has not always been rendered in historic texts where the lowercase form was present without any other diacritic, and some modern texts and font styles may still discard this "soft" dot on the lowercase letter, because it is necessary for the readability of the text only for cursive styles. == History == The Cyrillic soft-dotted letter i was derived from the Greek letter iota (Ι ι). The name of this letter in the Early Cyrillic alphabet was (''i/ižei''), meaning "and". In the Cyrillic numeral system, soft-dotted I had a value of 10. In the early Cyrillic alphabet there was little or no distinction between the Cyrillic letter i (И и), derived from the Greek letter eta, and the soft-dotted letter i. They both remained in the alphabetical repertoire because they represented different numbers in the Cyrillic numeral system, eight and ten respectively, and are therefore sometimes referred to as ''octal I'' and ''decimal I''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dotted I (Cyrillic)」の詳細全文を読む スポンサード リンク
