因
yīn
因 (because, due to)
Explanation
因 (yīn) is a preposition (a word placed before a noun to indicate a relationship) meaning 'because of', 'due to', used to state a cause, belonging to formal/written usage (a way of speaking used in books and documents, rarely used in speech).
因 + cause + (,) + result. The cause after 因 is usually a noun phrase or a short verb phrase: 因病 (yīn bìng: due to illness), 因公 (yīn gōng: due to official business).
in announcements, documents, and formal written sentences to explain a reason; often used with concise expressions like 因病请假 (take leave due to illness), 因故 (yīn gù: for some reason).
因 is formal and concise; 因为 (yīnwèi: because) is commonly used in colloquial speech and usually forms a full clause with a subject, whereas 因 tends to be attached to a short phrase (因病, 因公).
using 因 in everyday conversation sounds stiff (you should use 因为 instead); and avoid inserting a full sentence with a complete subject-predicate right after 因 as you would with 因为.
Examples
Due to the company's business needs, she has to go to China on a business trip.
Yesterday she took leave due to illness.
He was late because he left home too late.
