raikyaku no mae ni, daidokoro no syokki wo katadukemasita.

前に means before.

In this sentence, 来客の前に means before the guests came / before the arrival of visitors.

A helpful way to see it is:

• 来客 = visitors / guests / the arrival of guests
• の = links the noun to 前
• 前に = before

So the whole phrase works like a time expression: before the guests arrived.

This is a compact, somewhat formal-sounding way to say it. In everyday conversation, people might more often say something like お客さんが来る前に.

Here, の connects one noun to another.

• 来客 = guests / arrival of guests
• 前 = front / before

So 来客の前 literally becomes something like the before of the guests/guest-arrival, which naturally means before the guests came or before the arrival of guests.

This is a very common pattern in Japanese:

• 食事の前に = before the meal
• 出発の前に = before departure
• 試験の前に = before the exam

They are doing two different but related linking jobs.

1. 来客の前に

   • 来客 modifies 前
   • meaning: before the guests / before the guests arrived

2. 台所の食器

   • 台所 modifies 食器
   • meaning: the dishes in the kitchen or the kitchen dishes

So both の particles connect nouns, but they connect different pairs of nouns.

It most naturally means the dishes in the kitchen.

• 台所 = kitchen
• 食器 = dishes / tableware
• 台所の食器 = the dishes belonging to or located in the kitchen

In English, kitchen dishes can sound a little unnatural, so the dishes in the kitchen is usually the best translation.

Japanese A の B can express several relationships, including:

• location: 台所の食器 = dishes in the kitchen
• possession/belonging: 私の本 = my book
• category/type: 日本の車 = Japanese cars

Because 食器 is the direct object of the verb 片付けました.

• 食器を片付けました
• literally: put away / tidied up the dishes

The particle を marks the thing that the action is done to.

Examples:

• 本を読みました = read a book
• 部屋を掃除しました = cleaned the room
• 食器を片付けました = put away the dishes

片付けました is the polite past form of 片付ける.

片付ける can mean:

• to tidy up
• to put away
• to clear away
• to straighten up

In this sentence, it most likely means put away or cleared away the dishes.

So depending on context, the sentence could suggest:

• putting the dishes back where they belong
• clearing dishes away before guests arrived
• tidying the kitchen area

Because the sentence is describing a completed action:

• 片付けました = tidied up / put away

The speaker is saying that this action was done before the guests came.

Japanese often uses the past tense simply to report what happened, without needing extra words like did.

The subject is omitted, which is very common in Japanese.

The sentence does not explicitly say who did it. Depending on context, it could mean:

• I put away the dishes
• we put away the dishes
• someone put away the dishes

In many Japanese sentences, the subject is left out when it is already understood from the situation.

So even though English usually needs a subject, Japanese often does not.

来客 is correct, but it sounds a bit more formal or written than everyday casual speech.

A more conversational version would often be:

• お客さんが来る前に、台所の食器を片付けました。

That said, 来客 is a useful word and commonly appears in:

• signs
• notices
• formal writing
• business settings

So this sentence is natural, but it has a slightly formal feel.

Yes. In normal Japanese writing, it would usually be written without spaces:

来客の前に、台所の食器を片付けました。

The spaces in learning materials are often added just to make the parts easier to see.

Not always. It depends on what comes before it.

1. After a noun:

Use の前に

• 食事の前に = before the meal
• 来客の前に = before the guests / before the arrival of guests

2. After a dictionary-form verb:

Use verb + 前に

• 寝る前に = before sleeping
• 行く前に = before going
• お客さんが来る前に = before the guests come

So in this sentence, 来客 is treated as a noun, which is why it becomes 来客の前に.

Here are the standard readings:

• 来客 → らいきゃく
• 前 → まえ
• 台所 → だいどころ
• 食器 → しょっき
• 片付けました → かたづけました

So the full sentence is read:

らいきゃく の まえ に、だいどころ の しょっき を かたづけました。
