How it works

Basque knows no words for "twofold" and "threefold" — it says them like a householder, through the number of times. "Bi aldiz gehiago" — literally "two times more": aldiz — a time, from aldi — a spell. "Hiru aldiz gehiago" — three times more: the number is inserted into the ready-made frame.

To double is bikoiztu: from bi — two, the price "became a twosome": Prezioa bikoiztu da. And half is the old acquaintance erdia of wave 1: Erdia hartuko dut — I will take half, not the whole. After a number the article disappears: hiru metro — three meters, without -a.

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.
