Cause and effect with "yinwei" and "suoyi"

You will often come across “因为 (yīnwèi)... 所以 (suǒyǐ)..." in written Chinese as well as spoken Chinese. Better get used to it!

Structure

"因为 (yīnwèi) ... 所以 (suǒyǐ) ..." are used to indicate cause and effect. They are often thought of as being: "Since ___ happened, so ___ happened."

因为 + Cause , 所以 + Effect
