Learn Turkish: Elektrik kesintileri için jeneratör alsak iyi olur. - We had better buy a generator for power outages.

The phrase is made of al- (to buy) + -sa (if) + -k (we) + iyi (good) + olur (it becomes/is). Literally, it means "If we buy [a generator], it is good." In Turkish, this conditional structure (-sA iyi olur) is the standard way to express "had better" or to give a strong, practical suggestion.

Why is there an "-i" at the end of "kesintileri"?

This is the possessive suffix required for indefinite noun compounds. When you combine two nouns in Turkish to define a general concept—here, elektrik (electricity) and kesintiler (outages)—the second noun must take a possessive suffix to link them. Thus, kesintiler gets the third-person possessive -i, becoming elektrik kesintileri.

How is the noun "kesinti" (outage) formed?

It comes from the verb kesmek, which means "to cut." The suffix -inti (or -ıntı, etc.) is used to turn certain verbs into nouns that describe the result of an action. Therefore, a "cut" or "interruption" in a continuous flow becomes a kesinti.

The translation says "a generator", so why doesn't the Turkish sentence use "bir jeneratör"?

In Turkish, when a singular noun is the object of a verb and represents a general type of thing rather than one specific, emphasized item, the word bir (a/an) is often dropped. Saying jeneratör alsak means "if we buy [the category of item known as] generator," which sounds perfectly natural and idiomatic here.
