‘宿愿’ literally combines 宿 (sù), meaning ‘long-standing’ or ‘deep-rooted’, and 愿 (yuàn), meaning ‘wish’ or ‘aspiration’. Together, it refers to a wish that has been held for a long time—often since childhood, youth, or over many years—and carries emotional weight, sincerity, and sometimes a sense of destiny or quiet determination. It is more formal and literary than everyday words like 愿望 (yuànwàng) and implies depth, persistence, and personal significance.

This term appears frequently in written Chinese—such as essays, speeches, memoirs, or formal interviews—rather than casual conversation. It often describes aspirations tied to identity, values, or life goals: becoming a teacher, returning home after decades abroad, publishing a book, or reuniting with a long-lost family member. Because of its solemn tone, it’s rarely used humorously or lightly, and seldom paired with colloquial modifiers.
