1. 〜ために — the purpose you are working toward

Dictionary form + ために, or noun + の + ために. The action before ために is something you decide to do; the second clause is the effort you put in to get there.

noun + のI'm saving money for the wedding.
JapaneseEnglish
I'm studying Japanese in order to work in Japan.
I took out a loan to build a house.
