Learn Turkish: Masrafları azaltsak para biriktiririz. - If we reduced the expenses, we would save money.

In Turkish, present hypothetical conditions (like "if I did X") are formed by attaching the conditional suffix -sa or -se directly to the verb root, followed by the personal suffix. Here, we have the root azalt- + -sa + -k (we). This structure tells us the situation is hypothetical, rather than a real possibility.

Why is biriktiririz in the aorist tense (simple present) if the translation says "we would save"?

When setting up a present hypothetical scenario, Turkish pairs the -sa / -se conditional in the "if" clause with the aorist tense in the result clause. In these Type 2 conditional sentences, the aorist (here, -ir) functions exactly like "would" does in English.

Why is it masrafları instead of just masraflar?

The -ı at the end is the definite accusative suffix. It shows that we are talking about specific expenses ("the expenses"). Without it, masraflar would just mean expenses in general.

How is the verb azaltmak (to reduce) built?

It originates from the adjective az (little/few). Adding -al makes the verb azalmak (to decrease on its own). Adding the causative suffix -t turns it into azaltmak, which means "to make something decrease" or "to reduce."
