English

When the doer does not matter: …-tzen da

When the deed matters more than the doer, the object moves to the front and the auxiliary becomes da/dira. Etxe berriak saltzen dira hemen — new houses are sold here. The -tzen form is the process: it is done now, or in general. For example: “Etxe berriak saltzen dira hemen” — New houses are sold here. A rule from the Basque course: worked out on examples, not memorized as a wording.

How it works

When the deed matters more than the doer, the object moves to the front and the auxiliary becomes da/dira. Etxe berriak saltzen dira hemen — new houses are sold here. The -tzen form is the process: it is done now, or in general.

If the deed is already done, take the verb plus -tua izan da. Liburua euskarara itzulia izan da — the book has been translated into Basque. The doer can be named with -k: Jon-ek idatzia — written by Jon.

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.
