U+C7A4 "잤" Hangul Syllable Jass Unicode Character
U+C7A4 "잤" Hangul Syllable Jass is a precomposed syllable in the modern Korean writing system, representing the sound "jat" with a final "s" consonant, specifically the past or completed tense form of the verb stem "자-" (to sleep) combined with the sequential or past suffix "-ㅆ", thus meaning "slept" or "having slept". It belongs to the Hangul Syllables block in Unicode, which encodes all possible combinations of Korean initial consonants, vowels, and final consonants as single coded characters for efficient text processing. This character is composed of the initial consonant "ㅈ" (j), the vowel "ㅏ" (a), and the final consonant cluster "ㅆ" (ss), and it is used in written Korean to denote an action that has already occurred, such as in the sentence "어제 일찍 잤다" meaning "I slept early yesterday."
