额外

• Pinyin: é wài
• Hanzi breakdown: 额 = 革 (top-of-head area) + 客 (guest, phonetic) — forehead, extended to fixed amount/quota; 外 = 夕 (evening) + 卜 (divination) — that which is outside the expected

Meaning

Extra; additional; beyond the usual or required amount. Outside the normal scope or quota.

额外 is commonly used in workplace, financial, and contractual contexts. It describes what exceeds an established baseline: 额外费用 (extra fees), 额外工作 (additional work), 额外福利 (extra benefits). It is more formal and precise than 多余 (excess/surplus).
