Questions & Answers about eki de kippu o nimai kaimashita.

Why is で used after 駅?

で marks the place where an action happens.

In this sentence, 駅で means at the station as the location of the action buying.

A helpful contrast:

• で = where an action takes place
  
  • 駅で買いました = bought it at the station
• に = destination, time, or existence in many cases
  
  • 駅に行きます = go to the station

So here, because the speaker is doing the action of buying at the station, で is the natural particle.

Why is を used after 切符?

を marks the direct object of the verb—the thing that the action is done to.

Here, the action is buying, and the thing being bought is 切符 (ticket(s)), so:

• 切符を買いました = bought ticket(s)

In other words, 切符 is what was bought, so it takes を.
