Questions & Answers about Trenin varış saati değişmek üzere.
How does üzere work here to mean "about to"?
When the word üzere follows a verb in its full infinitive form (ending in -mak or -mek), it creates the meaning of "about to" or "on the verge of" doing that action. Here, değişmek üzere means "is about to change".
How is the word varış formed?
It is created from the verb varmak (to arrive or to reach). Adding the suffix -Iş turns a verb into a noun that represents the action itself. So, varış translates directly to "arrival".
Why is it varış saati instead of just varış saat?
This is a standard noun compound. The word varış (arrival) describes what kind of saat (time) it is. In Turkish, when two nouns are paired like this, the second noun requires a possessive suffix. The -i on saati is that suffix, linking the time to the arrival.
Why does Tren have the -in suffix here?
The -in suffix shows possession (the genitive case), meaning "the train's". It links the train to its arrival time. The whole phrase forms a chain of possession: Trenin (the train's) varış saati (arrival time).
