Unicode Version 17.0

啟

U+555F "啟" CJK Unified Ideograph-# is a traditional Chinese character that primarily means "to open," "to begin," or "to enlighten," and it is commonly used in classical and modern written texts across East Asia, including Chinese, Japanese, and Korean. This character is composed of two main components: the radical "攵" on the right, which is associated with action or striking, and the left side "啟" which itself comprises "户" (door) and "口" (mouth), together conveying the idea of opening a door to speak or to initiate a process. In historical contexts, "啟" also carries connotations of informing or advising, as seen in phrases like "啟示" (revelation) or "啟發" (inspiration), and it is frequently encountered in formal documents, literature, and personal names, reflecting its enduring significance in conveying the concept of commencement or enlightenment.
