Preposition/Conjunction 由于 (Due to / Owing to / Because of)

Pattern

• 由于 + Reason，Subject + 因此 + Result
• 由于 + Reason，所以 + Result

Usage

• 由于 (yóuyú) is a preposition and causal conjunction meaning “due to”, “owing to”, or “because of”.
• Compared to 因为 (because - informal and everyday), 由于 is distinctly more formal, objective, and scholarly, frequently seen in official notices, reports, news, and essays.
• Standard structure: 由于 + Cause, (因此 / 因而 / 所以) + Result.
• In formal style, the result clause typically favors 因此 (therefore) or 因而 (consequently) rather than the casual 所以.
