U+55EF "嗯" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

嗯

U+55EF "嗯" CJK Unified Ideograph-# is a Chinese character that functions primarily as an interjection or a response particle in spoken and written Chinese, commonly representing a nasal sound of acknowledgment, agreement, hesitation, or thoughtful consideration, akin to saying "hmm" or "uh-huh" in English. Its semantic composition combines the mouth radical 口 (kǒu) with a phonetic component, emphasizing its role in vocal expression rather than denoting a concrete object or concept. Across various Chinese dialects and contexts, the character's tone and usage can convey subtle emotional nuances, from simple affirmation to mild surprise or skepticism, making it a versatile and frequently used element in everyday discourse, including digital communication where it often appears as a single-character reply.
