Learn Finnish: Tilanne jäi pysyväksi, joten meidän täytyi tottua siihen. - The situation became permanent, so we had to get used to it.

The verb jäädä (to remain, to stay) takes the translative case (-ksi) when expressing the state, role, or condition that something ends up in. Even though "remaining" implies that a state doesn't change, Finnish grammar treats the final settled condition as a resulting state.

The verb jäädä usually means "to stay" or "to remain." Why is it translated as "became" here?

While jäädä pysyväksi literally means "remained permanent," the most natural English translation is often "became permanent." In Finnish, jäädä plus the translative case is the standard idiom for expressing that a temporary or uncertain situation has finally settled into a lasting state.

Why is the subject "we" translated as meidän (genitive) instead of me (nominative)?

This is due to the necessity verb täytyi (had to). In Finnish, verbs expressing necessity, obligation, or duty (like täytyy, pitää, and tarvitsee) require the person doing the action to be in the genitive case. Therefore, me becomes meidän.

Why is the pronoun se (it) in the illative case (siihen) at the end of the sentence?
