Practice JLPTHow to tell them apart
ために attaches to a volitional action or noun that the subject actively carries out, while ように describes a state or outcome you want to bring about, often involving someone else or an ability. Use 研究のためにドイツに行く when you do the action yourself for that purpose; use 分かるようにゆっくり話す when the goal is a resulting condition, not your own direct action. Swapping them sounds unnatural because ために cannot link to non-volitional verbs like 分かる.
- 為（に）・ため（に） Use ために when the subject performs a deliberate action to achieve their own purpose.
- ように Use ように when the goal is a state or outcome, especially one outside your direct control.
