Questions & Answers about kaikei no mae ni, kurejittokaado o junbishite okimasu.

Why is there の in 会計の前に?

Because 前 is a noun, and when you put one noun before another noun in Japanese, you usually connect them with の.

• 会計 = checkout / payment
• 前 = before / front

So 会計の前 literally means the before of the checkout, or more naturally, before checkout / before paying.

This pattern is very common:

• 食事の前に = before the meal
• 寝る前に = before sleeping
  
  • with verbs, you use the dictionary form directly before 前に
• テストの前に = before the test

Why is there に after 前?

In 会計の前に, the に marks the time point relative to which the action happens.

So:

• 会計の前に = before checkout
• 会計の前 by itself is more like the time before checkout as a noun phrase

With time expressions like 前 and 後, に is very common when you want to say when something happens.

Compare:

• 食べる前に、手を洗います。 = Before eating, I wash my hands.
• 帰った後に、電話します。 = After returning, I’ll call.

In casual speech, に is sometimes dropped in some expressions, but for learners, using it here is the safest and most standard choice.
