见于

见于 is a prepositional phrase meaning 'found in' or 'appears in.' It is commonly used to indicate where something can be found, such as in texts, documents, or sources.

The character 见 (jiàn) originally meant 'to see,' but in this context, it functions as a prefix indicating occurrence or presence. The character 于 (yú) means 'in' or 'at,' and together they form a phrase that indicates location or source of information.

见于 is often used in academic or formal writing to cite sources or locations. For example, it might appear in research papers or dictionaries to show where a term is documented. It is also useful in legal or historical contexts to specify where an event or statement was recorded.
