U+6C9F "沟" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

沟

U+6C9F "沟" CJK Unified Ideograph-# is a Chinese character that primarily means "ditch," "trench," or "gutter," often referring a narrow channel or groove dug into the ground for water drainage, irrigation, or as a natural geographical feature like a ravine. It is composed of the radical for water (氵) on the left, indicating its association with flowing water, and the phonetic component 勾 on the right, which provides a clue to its pronunciation, roughly "gōu" in Mandarin Chinese. This character is commonly used in modern Chinese vocabulary, appearing in words such as 沟通 (gōutōng, meaning communication or connection) and 水沟 (shuǐgōu, meaning ditch or drain), illustrating its practical and metaphorical applications in describing both physical channels and figurative linkages.
