Language View
In your native language
English often expresses purpose with to + verb, in order to, so that, and for + noun/gerund.
I came here to learn.
to learn = purpose
In your learning language
Purpose is expressed with para + infinitive or para que + subjunctive when subjects differ.
Estudio para aprender. Te llamo para que vengas.
I study to learn. I call you so that you come.
Learners often miss the subjunctive after para que or confuse por and para.
