【棄嫌】的英文翻譯可以是 **"discard as undesirable"** 或 **"reject as unsuitable"**。

具體選擇哪個翻譯，取決于上下文：

1. **"discard as undesirable"** - 強調因為不滿意、不想要而丟棄。
2. **"reject as unsuitable"** - 強調因為不合適、不達標而拒絕。

**例句：**
- 他因為一點小毛病就棄嫌了那臺舊電腦。
- He **discarded the old computer as undesirable** because of a minor flaw.
- 招聘方不應因年齡而棄嫌有經驗的應聘者。
- Employers should not **reject experienced candidates as unsuitable** because of their age.

如果需要更簡潔或口語化的表達，也可以根據具體語境使用 **"get rid of"**、**"throw away"** 或 **"reject"**，但會損失“因嫌棄而放棄”的細微含義。
