源于……

源于…… means "originate from; stem from" and is used with the frame A 源于 B. Use it when you need to express this exact logical relation: A originates from B. Do not use it as a loose translation word; first check whether the two parts of the sentence really match the relation. Common mistakes include dropping 于 in 于-phrases, putting the key word after the object, or confusing similar patterns such as 来自, 归因于, 始于. In formal writing, keep the clauses complete and avoid mixing two cause-result connectors unless the sentence truly needs both.
