• enhance 本词

  Focuses on improving quality, value or appeal rather than a countable amount; used with abstract nouns like flavor, mood, experience or reputation; sounds more formal and polished.

  侧重提升质量、价值或吸引力，而非增加可数的数量；常与风味、氛围、体验、声誉等抽象名词搭配，语气更正式、精致。

• heighten

  Means to intensify an existing feeling, sensation or effect, such as tension, awareness or suspense; common in descriptive or literary writing, not used for numbers.

All three mean to make something greater. Raise is used for measurable things like money or prices, not its meanings 'lift up' or 'bring up children'. Enhance means improving quality or value, like flavor. Heighten means making a feeling or effect stronger, like tension.

这三个词都可以译为“提高”，但用法不同：raise 用于可量化的具体事物（如工资、价格），enhance 强调提升质量或价值，heighten 强调加强某种已有的感觉或效果（如紧张感）。这里不比较 raise 表示“举起”或“抚养”的义项。
