Breakdown of tā de xìnggé hěn ānjìng, dànshì duì xuéxí de tàidu hěn hǎo.

What exactly does 性格 (xìnggé) mean, and how is it different from words like 个性 (gèxìng) or 性情 (xìngqíng)?

性格 means “character” or “personality” – the relatively stable way someone tends to behave or react.

性格: the neutral, everyday word for personality.
- Examples:
  - 他性格很安静。= His personality is very quiet.
  - 她性格很开朗。= Her personality is very cheerful.
个性: closer to “individuality / personal style”, often with a feeling of being distinctive or unique.
- 他很有个性。= He’s very individual / has a strong personality.
性情: more about temperament / emotional nature, slightly more literary.
- 他性情温和。= His temperament is gentle.

In this sentence, 性格 is the most natural and neutral choice to talk about what he is like as a person in general.

Why say 他的性格很安静 instead of just 他很安静? Is there a difference?

Both are correct, but they focus on slightly different things:

他很安静。
- Literally: He is very quiet.
- This can describe:
  - his general personality, or
  - his state/behavior in a particular situation (e.g., “He’s being very quiet right now”).
他的性格很安静。
- Literally: His personality is very quiet.
- This makes it clear that you are talking about his underlying character, not just how he acts in one moment.

So using 性格 emphasizes a stable trait (“by nature he is quiet”), not just temporary behavior.
