Learn Turkish: Radyasyon kalkanı kırılmak üzere, ne var ki yerleşke hâlâ güvenli. - The radiation shield is about to break, however the settlement is still safe.

Ne var ki translates to "however," "nevertheless," or "that being said." It introduces a contrast, but with a slightly more formal or emphatic tone of reservation than a simple ama (but). It fully acknowledges the urgency of the first clause (the shield breaking) before offering the mitigating counterpart (the settlement being safe).

I know üzere often means "in order to." Does it mean something else in kırılmak üzere?

Yes! When paired with an infinitive verb (-mak / -mek) and used as the main predicate of a sentence, it means "about to" or "on the verge of." Since kırılmak is the verb "to break," kırılmak üzere means the shield is right on the verge of breaking.

Where does the word yerleşke come from?

It is derived from the verb yerleşmek (to settle). The suffix -ke is added to certain verbs to create nouns that denote a specific place or location where that action happens. It usually translates to "settlement," or in educational contexts, a university "campus."

Why is the sentence ending with just güvenli instead of güvenlidir?
