U+318D "ㆍ" Hangul Letter Araea is a rarely used vowel symbol from the Korean Hangul writing system, representing a short, low, or neutral vowel sound that does not occur in modern standard Korean. Historically part of the original 15th century Hangul alphabet, this letter was used to transcribe the sound of the Middle Korean vowel commonly romanized as "arae a," which is distinct from the modern vowel "a" (ㅏ). Today, it is primarily encountered in historical linguistic texts, period documents, and specialized typography, and it remains an important component for accurately representing older forms of the Korean language.
