Learn Turkish: Ben parkta kaykaya binebilirim. - I can ride a skateboard in the park.

In Turkish, the verb binmek (to ride, board, or get on) always requires the object you are getting on to have the dative case suffix, which means "to" or "towards". You use it for cars, bikes, horses, and skateboards. So you aren't just riding a skateboard, you are getting "onto" the skateboard (kaykaya).

How does the word binebilirim mean "I can ride"?

The "can" meaning comes from the ability suffix -ebil. It is added directly to the verb root bin- (to ride) to make binebil- (can ride).

What does the -ir- do in the middle of binebilirim?

That is the aorist tense suffix, which is used for general facts, habits, and abilities (similar to the English simple present). When stating that you have the general ability to do something, Turkish pairs the ability suffix (-ebil) with the aorist tense (-ir), followed by the personal ending (-im for "I").

Why is it parkta instead of parkda?

This is a quick reminder of the consonant harmony rule. Because the word park ends in a hard, voiceless consonant (k), the locative suffix -da (meaning "in" or "at") must change its starting letter to a hard t, making it -ta.
