The purpose looks forward: -tzeko and the complex sentence

To say WHY you came, Basque grows the suffix -tzeko onto the verb: Iketzeko etorri naiz — I came to study, literally "for-studying I came". Inside is the verbal noun in -tzea (waves 2–4 already built it: laguntzea, garbitzea) plus -ko — "for". For example: “Iketzeko etorri naiz” — I came to study. A rule from the Basque course: worked out on examples, not memorized as a wording.

How it works

To say WHY you came, Basque grows the suffix -tzeko onto the verb: Iketzeko etorri naiz — I came to study, literally "for-studying I came". Inside is the verbal noun in -tzea (waves 2–4 already built it: laguntzea, garbitzea) plus -ko — "for".

The -tzeko form can also stand in front: Bisata lortzeko paperak behar dira — to get the visa, papers are needed. The main verb stays behind — the language keeps the purpose before the eyes and the manner after: the purpose looks forward, the reason (wave 4, -lako) — back.

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
