U+3163 "ㅣ" Hangul Letter I Unicode Character
Unicode Version 17.0
ㅣ
U+3163 "ㅣ" Hangul Letter I is a vowel jamo, or basic letter, from the Korean Hangul script that represents the phonetic sound [i], similar to the long "ee" in the English word "see". In the original composition of Hangul, its shape was inspired by the sky, earth, and man principle, with the vertical stroke symbolizing a human standing upright. As a modern jamo, it can be used independently to write the syllable "i" in Korean, but it is most frequently combined with initial consonants to form complete syllabic blocks in words like "이" (meaning "this" or "tooth"). This character is distinct from the visually similar Latin lowercase "l" and should not be confused with the Hangul letter "ㅏ" which represents an "ah" sound.
