Learn Turkish: Yol boyunca gördüğüm her şey bana hüzünlü çocukluğumu anımsatacak. - Everything I see along the way will remind me of my sad childhood.

In Turkish, the -DIK participle covers past and present (non-future) events. Although the main verb anımsatacak is future, the act of "seeing" is framed as a general occurrence ("whatever I see") happening concurrently with the journey. Using göreceğim her şey would sound more rigidly like "everything I am scheduled to see later."

How is the phrase yol boyunca put together?

It is built from yol (road/way) and boyunca. The word boyunca comes from boy (length), the possessive -u, the buffer -n-, and the equative suffix -ca. Literally translating to "along its length," it is a very common postposition meaning "along the way" or "throughout."

What is the function of the -t in anımsatacak?

It is the causative suffix. The base verb is anımsamak, meaning "to remember" or "to recall." By adding -t, it becomes anımsatmak ("to cause someone to remember"), which is the standard way to say "to remind."

Why is bana (to me) in the dative case here?
