Questions & Answers about houmonyoteijikan o kime shidai, renrakushimasu.

How do you read this sentence?

It is read:

訪問予定時間を決め次第、連絡します。
ほうもんよていじかん を きめしだい、れんらくします。

In normal Japanese writing, it would usually appear without spaces: 訪問予定時間を決め次第、連絡します。

What exactly is 訪問予定時間?

It is a compound noun made of:

• 訪問 = visit
• 予定 = plan / schedule
• 時間 = time

So 訪問予定時間 means something like the scheduled time for the visit or the appointment time for the visit.

Japanese often stacks nouns together like this, so you do not need extra particles inside the compound.

Why is the particle を used here?

Because 決める is a transitive verb, meaning it acts on something.

Here, the thing being decided is 訪問予定時間, so it takes を:

訪問予定時間を決める = to decide the visit time

So を marks 訪問予定時間 as the direct object of 決める.

Why is it 決め instead of 決める?
