Must and can: behar and -ke
Necessity is built by the verb behar + the main verb in the perfect form: Joan behar dut — I must go, literally "to go I-have-need". The object lives in the auxiliary, as wave 2 taught: Erosi behar ditut — I must buy them. For example: “Joan behar dut lanera orain” — I must go to work now. A rule from the Basque course: worked out on examples, not memorized as a wording.
How it works
Necessity is built by the verb behar + the main verb in the perfect form: Joan behar dut — I must go, literally "to go I-have-need". The object lives in the auxiliary, as wave 2 taught: Erosi behar ditut — I must buy them.
Possibility hides in the auxiliary too: -ke. Ireki dezaket? — may I open? Etor daiteke — he may come, a faceless "one can". The negation of possibility has its own word: Ezin dut etorri — I cannot come (wave 1 already said it this way).
The pair divides the work honestly: "behar" is about necessity, "-ke" is about permission and ability.

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.
