How to Understand
由于
由于 is a preposition meaning 'because of' or 'due to.' It introduces the reason for an action or situation, often used in formal or written contexts.
The character 由 (yóu) originally meant 'to originate from' or 'to be caused by,' while 于 (yú) is a classical preposition indicating 'in relation to' or 'regarding.' Together, they form a fixed expression that conveys causation or explanation.
由于 is commonly used in news articles, academic writing, and formal speeches. It is more formal than the spoken equivalent '因为 (yīn wèi).' In daily conversation, it may sound slightly more structured or literary, but it is still widely understood and used.
