How it works

The reason is a suffix grown onto the word. After a noun stands -gatik: euriagatik — because of the rain, isunagatik — because of the fine. After a verb form — -lako: Nekatuta nagoelako ez naiz joan — I did not go because I was tired: the tiredness hides inside the word itself.

An action-cause turns into a noun through -tzea and takes the same -gatik: Eskerrik asko laguntzeagatik — thanks for the help. The purpose lives separately: -tzeko: Lan egiten dut familia mantentzeko — I work to support the family. The reason looks back, the purpose looks forward; the suffixes cannot be mixed up.

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.
