Questions & Answers about hoteru ga heya o kakuhoshita.

Why is が used after ホテル?

が marks the grammatical subject of the sentence: the thing that performs the action.

So in ホテルが部屋を確保した, ホテル is the subject, meaning the hotel is the one that secured or set aside the room.

A learner often compares が and は here:

• ホテルが = emphasizes the hotel as the doer
• ホテルは = would make the hotel the topic, with a slightly different feel

In an isolated sentence like this, が is very natural for introducing who did the action.

Why is を used after 部屋?

を marks the direct object: the thing directly affected by the action.

Here:

• 部屋 = room
• 部屋を = the room is what was secured

So the structure is:

• ホテルが = the hotel did it
• 部屋を = the room was acted on
• 確保した = secured

Does this mean the hotel itself secured the room? That sounds a little strange in English.
