悠久

• Pinyin: yōu jiǔ
• Hanzi breakdown: 悠 = 忄+ 攸 (heart + flowing far — remote, long-stretching); 久 = person-from-behind (long duration)

Meaning

Long-standing; of great historical depth; stretching far back in time. Describes civilisations, traditions, cultures, or relationships of considerable antiquity.

Almost exclusively used to describe positive or neutral things of great age: 历史悠久 (long history), 悠久的文明 (ancient civilisation), 悠久的传统 (age-old tradition). Not used for negative phenomena growing over time. Carries a tone of admiration and cultural pride. A near-synonym is 源远流长 (with deep roots and long flow — also implies continuous vitality).
