How it works

To say that a person was busy with something for some time, Basque has the verb aritu — "to be in the business": the verb in -tzen plus aritu. Igandean korrika aritu gara — on Sunday we ran, literally "running we were situated".

The form changes by persons and tenses, like an ordinary verb: aritu naiz — I was busy, aritu da — he was busy, arituko gara — we will be busy. Often a term stands nearby: negu osoan entrenatzen aritu da — all winter he trained. The process here is a place where a person spent time.

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.
