"大敗" 的英文翻譯可以根據(jù)具體語(yǔ)境選擇以下表達(dá)：

1. **Defeat decisively** / **Crush**（強(qiáng)調(diào)徹底擊敗）
- 例：我軍大敗敵軍。 → *Our army decisively defeated the enemy.*

2. **Suffer a major defeat**（強(qiáng)調(diào)遭受慘敗）
- 例：客隊(duì)大敗而歸。 → *The visiting team suffered a major defeat.*

3. **Rout**（尤指潰敗、擊潰）
- 例：比賽以大敗告終。 → *The game ended in a rout.*

4. **Overwhelming defeat**（壓倒性失敗）
- 例：選舉中大敗對(duì)手。 → *They handed their opponents an overwhelming defeat in the election.*

**注意**：
- 若"大敗"后接賓語(yǔ)（如"大敗某人"），通常用 **defeat/crush/rout** + 對(duì)象。
- 若主語(yǔ)是失敗方，需用 **suffer a defeat** 結(jié)構(gòu)。
