Learn Turkish: Cesur asker ölmek pahasına savaşır. - The brave soldier fights at the cost of dying.

The root is paha (price/value). We add the third-person possessive suffix -sı, the buffer letter -n-, and the dative case -a, creating pahasına. When following a full infinitive like ölmek, it means doing something 'at the cost of' or 'at the risk of' that action.

Is paha related to the word pahalı?

Yes, they share the same root. While pahalı means 'expensive' (literally 'with a price'), the root noun paha is used in this grammar structure to represent the heavy toll or price an action might demand.

The lesson mentions using a noun with pahasına. How would that look in this sentence?

Instead of the infinitive ölmek (to die), you could use a noun phrase like canı (his life/soul). Saying canı pahasına savaşır means 'he fights at the cost of his life,' which is a very natural and common Turkish idiom.

Why use the aorist tense savaşır instead of the present continuous savaşıyor?

This sentence states a general truth or a defining characteristic of a brave soldier, rather than an action happening right at this moment. The aorist tense is the best choice in Turkish for proverbs, general facts, and timeless statements like this.
