Questions & Answers about jitensha o chuurinjou ni oite kara, eki made arukimasu.

Why is を used after 自転車?

を marks the direct object of the verb.

Here, the verb is 置く (おく) = to put / place / leave.
So 自転車を置く means to put/leave the bicycle.

In other words:

• 自転車 = bicycle
• を = marks what is being acted on
• 置く = to place / leave

So 自転車を tells you that the bicycle is the thing being left in the parking area.

Why is に used after 駐輪場 instead of で?

With 置く, に marks the place where something is placed.

So:

• 駐輪場に置く = put/leave it in the bicycle parking area

This is different from で, which often marks the place where an action happens.
But with verbs of placement like 置く, に is the normal choice because it marks the destination/location where the object ends up.

Compare:

• 机に本を置く = put a book on the desk
• 部屋で勉強する = study in the room

So in this sentence, 駐輪場に is the correct grammar.

What does 置いてから mean exactly?
