Expressing purpose with "weile"

为了 (wèile) is most often used to indicate the purpose of an action, or the person that will benefit from some act of kindness. In the "purpose" sense, it corresponds pretty well to "in order to" or "for the purpose of" in English.

为了 as a preposition

When 为了 indicates the purpose of an action, it's usually acting as a preposition. In this role, the whole "为了 phrase" should come before the verb.

Note also that 为了 is a single word; the 了 here is not serving its role as a particle in this case.
