Learn Turkish: Sarı gaga şu kuşa ait olabilir. - The yellow beak might belong to that bird.

The word olabilir is made of the verb root ol- (to be), the possibility suffix -abil, and the aorist suffix -ir. When the possibility suffix is followed by the aorist tense, it expresses probability or an educated guess. Here, it changes "is" to "might be."

Why do we use olabilir (might be) when the English translation says "might belong"?

Turkish doesn't have a single verb for "to belong." Instead, it uses the word ait (belonging) combined with the helper verb olmak (to be). So, "might belong" is literally expressed as "might be belonging" (ait olabilir).

Why does kuş (bird) have the -a suffix to become kuşa?

The word ait always requires the noun before it to be in the dative case (the "to" direction). Since kuş ends in a hard consonant, we add the dative -a to make kuşa. You can think of it as "belonging TO the bird."

Why use şu instead of o for "that" bird?

While both mean "that," şu is specifically used to draw someone's attention to something they aren't looking at yet, or to physically point at something visible nearby. The speaker is likely pointing their finger at the bird right now.
