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!

== 为了 ==

为了 can be used to mean "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." It can be put in the beginning or end of a sentence, and it can also be placed after the subject. 

=== Structure ===

为了 + Purpose，Subj. + Predicate
