U+53F9 "叹" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
叹
U+53F9 "叹" CJK Unified Ideograph-# is a Chinese character that primarily means "to sigh" or "to exclaim," often conveying a sense of emotion such as regret, admiration, or wonder. It is composed of the radical 口 (mouth) on the left, indicating speech or vocal expression, and the phonetic component 欠 (to owe or lack) on the right, which contributes to its pronunciation as "tàn" in Mandarin. This character appears in common words like 叹息 (tànxī, "to sigh deeply") and 感叹 (gǎntàn, "to sigh with emotion"), and it is widely used in both classical and modern Chinese texts to express a heartfelt response to a situation or thought.
