Meaning (意思 yìsi)
Conjunction 因此 is used to connect cause and result, carrying the formal meaning of 'therefore', 'consequently'.
Explanation (解释 jiěshì)
因此 is a conjunction (连词) used to express a result or consequence in a formal register. It means "therefore," "thus," or "as a result."
Compared to 所以, 因此 is more commonly used in written language, speeches, or situations requiring formality, emphasizing a tight logical relationship between cause and effect. The clause containing the cause is typically stated in full before 因此 is used to introduce the conclusion.
