于是
How to Understand
于是 is an adverb that means 'therefore' or 'so,' used to indicate a result or consequence of a previous action or situation. It connects two related events, showing cause and effect.
The character 于 (yú) originally meant 'at' or 'by,' and is often used in classical Chinese to indicate location or time. The character 是 (shì) means 'is' or 'to be.' Together, 于是 conveys the idea of 'at this point' or 'as a result,' functioning as a conjunction in modern Chinese.
于是 is commonly used in both spoken and written Chinese to link ideas logically. It appears frequently in narratives, explanations, and everyday conversations to show the outcome of an action. For example, it might be used when explaining why something happened or what followed from a particular decision.
