Definition
宿敌 (sù dí) refers to a long-standing enemy or rival, not simply a 'old' enemy as in 'elderly' — the 宿 here implies duration (e.g. 宿怨 'long-held grudge') rather than age. This word is commonly used in political, historical, or competitive contexts (e.g. 体育界的两支宿敌队). You can think of it as 'arch enemy' or 'sworn enemy' — someone you've been opposing for a long time.
