Comparing "weile" and "yinwei"

为了 (wèile) and 因为 (yīnwèi) both have the character "为" in them, and they have sort of similar meanings: 为了 means "in order to" and 因为 means "because." Using them properly is important if you want to master Chinese!

Used as an Conjunction

The simplest definition of 因为 is "because." When used at the beginning of a sentence, it is often used with 所以 (which can mean "therefore" or "as a result") to express a cause and effect relationship.

为了 means "in order to," basically expressing some purpose. In English we may say some things like: "In order to get fit, I will go jogging every day." 为了 can also be placed after the subject.
