Tomorrow: the future tense

The future is built in two moves: the future stem of the verb + the auxiliary. The stem is made by the suffix -ko: erosiko dut — I will buy, ikusiko dut — I will see.

How it works

The future is built in two moves: the future stem of the verb + the auxiliary. The stem is made by the suffix -ko: erosiko dut — I will buy, ikusiko dut — I will see. If the stem ends in -n, the suffix sounds -go: joango naiz — I will go, egingo dut — I will do.

The auxiliary is the same one as in the present: for "go-be" — naiz, zara, da, gara; for actions with an object — dut, du, ditut. Only the meaningful part changes: Donostiara noa — I am going to Donostia, Donostiara joango naiz — I will go to Donostia.

Negation and the question stay in place: Ez naiz joango — I will not go, Noiz joango zara? — when will you go? There is no split like English "will go / will be going" here: one form covers both.

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.
