Learn Turkish: Baykuş ağaca konabilir. - The owl might perch on the tree.

The suffix -abil combined with the aorist tense (the -ir at the end) is used to express both ability ("can") and possibility ("might"). In Turkish, you rely on context to tell them apart. Here, we are stating a probability about what the owl will do, so it translates best as "might".

Why does the Turkish use the dative case in ağaca (to the tree) instead of the locative case ağaçta (on the tree)?

The verb konmak (to land, settle, or perch) implies movement toward a destination. In Turkish, verbs of motion or placement usually require the dative case (-a or -e) to show where the subject is going, even if English uses "on". If the owl were already perched and just sitting there, you would use the locative case with a different verb.

The word for tree is ağaç. Why does it change to ağaca here?

This is a reminder of consonant mutation (often called the k-t-ç-p rule). When a word ends in a hard consonant like ç and you add a suffix starting with a vowel (like the dative -a), the hard consonant softens to its voiced pair to make pronunciation smoother. Therefore, ç becomes c.

Is the verb konmak only used for birds?

It is very commonly used for birds and insects landing, but its general meaning is "to land" or "to settle". You can also use it for dust settling on a surface, or even a person temporarily settling in a location.
