(Redirected from И)
'I' or 'Y' ('И', 'и') is a letter in the
Cyrillic alphabet, representing in Russian and in Ukrainian. It is derived from the
Greek letter
eta (''Η, η'' representing in
Ancient Greek and in
Modern Greek).
Origins
In the
early Cyrillic alphabet there was little or no distinction between the letters И ''(izhe)'' and І ''(i)'', descended from the Greek letters Η ''(eta)'' and Ι ''(iota)''. They both remained in the alphabetical repertoire because they represented different numbers in the
Cyrillic numeral system, eight and ten, and are therefore sometimes referred to as ''octal I'' and ''decimal I''.
Usage
It is the tenth letter of the
Russian alphabet, and in
Russian it represents , like the ''i'' in mach'i'ne. Although in isolation it is not preceded by the semivowel like other "soft" vowels (
'е',
'ё',
'ю', and
'я'), in Russian it is considered the soft counterpart to
'ы', which represents , because it denotes a preceding soft consonant. In
Ukrainian and
Belarusian, the sound is represented by the letter
'і', sometimes called ''Ukrainian I''.
The letter и is the eleventh letter of the
Ukrainian alphabet.
Belarusian has dispensed entirely with the letter и.
With a
breve, it forms the letter
'й', called ''I kratkoye'' ("short I") in
Russian, similarly ''I kratko'' in
Bulgarian, or ''Yot'' in Ukrainian and it represents the 'y' in English "bo'y'."
It is
transliterated from Russian as 'i', or from Ukrainian as 'y' or 'i', using different
romanization systems. See

romanization of Ukrainian.
Shape
Originally, Cyrillic 'И, и' had the shape identical to Greek uppercase 'Η' or Latin uppercase 'H'. Later, the middle stroke turned counterclockwise which made the modern form similar to the mirrored
Latin alphabet's capital '
N' (this is why 'И' is used in
faux Cyrillic typography). But style of the two letters is not fully identical: in Roman-type fonts, 'И' has serifs on all four corners, whereas 'N' only on bottom-left and top-right ones; also, 'И' has (contrarily to 'N') thicker vertical lines than the diagonal one. Lowercase 'и' in regular fonts has the same shape as uppercase 'И'. In italic (cursive) fonts, lowercase ''и'' may look like Latin ''u''. In handwritten (calligraphic) fonts, both lower- and uppercase forms of ''и'' have usually the shape of handwritten Latin lowercase ''u''.
