因此 (therefore)

• 拼音: yīncǐ
• 结构: Cause ，因此 + Effect / Result
• 汉字拆解: 因 = 囗 (enclosure) + 大 (big) — a person confined, suggesting cause ; 此 = 止 (stop) + 匕 (spoon) — pointing to 'this'

含义

The conjunction 因此 (yīncǐ) means 'therefore,' 'thus,' or 'for this reason.' It appears at the beginning of a result clause to formally state the consequence of a previously mentioned cause. It is more formal than 所以.

因此 is the formal equivalent of 所以 and is widely used in written Chinese, academic papers, news reports, and official speeches. While 所以 is perfectly natural in casual conversation, 因此 sounds more polished and deliberate. It typically follows a statement of cause and introduces the logical result. Unlike 所以, 因此 does not require a preceding 因为 — it can connect two independent sentences where the causal relationship is clear from context. Learners should note that 因此 is rarely used in informal daily conversation and may sound overly stiff in casual settings. It is sometimes interchangeable with 因而, though 因而 is even more literary.

例句

1. 他平时很努力，因此成绩一直很好。
2. 这条路正在施工，因此我们需要绕道走。
3. 她有丰富的经验，因此很快就解决了问题。

The word 因此 combines 因 (because, cause) and 此 (this), literally meaning 'because of this.' It has been a staple of formal Chinese writing since the classical period, used to draw logical conclusions from stated premises.
