uketuke no hito ha teineina iikata de kaigisitu no basyo wo osiete kuremasita.

Literally, 受付の人 means the person at reception or the person at the front desk.

In many situations, the most natural English translation is the receptionist, but Japanese is a little less specific here. It does not necessarily focus on the person’s job title; it just identifies them as the person working at the reception area.

• 受付 = reception, front desk
• 人 = person
• 受付の人 = person at the reception desk

は marks 受付の人 as the topic of the sentence.

The sentence is basically saying, As for the person at reception, they told me where the meeting room was in a polite way.

This does not always match English subject marking exactly. Here, は sets up the person at reception as the thing the sentence is talking about.

If you are wondering about は vs が, a simple way to think about it is:

• は = topic, what we are talking about
• が = often marks the grammatical subject more directly, especially when introducing new information or identifying something

So 受付の人は feels very natural here.

In both places, の connects nouns.

1. 受付の人

   • literally person of reception
   • natural English: person at reception

2. 会議室の場所

   • literally location of the meeting room
   • natural English: the location of the meeting room or where the meeting room is

A very important point is that の is not always just possession. It can show many kinds of relationships between nouns, such as:

• possession
• category
• location/association
• description

So here it is better to think of の as a general noun-linking particle.

Because 丁寧 is a na-adjective.

When a na-adjective directly modifies a noun, it takes な:

• 丁寧な言い方 = a polite way of speaking

If you want to modify a verb instead, you use に:

• 丁寧に教えてくれました = explained it politely

So:

• 丁寧な + noun
• 丁寧に + verb

That is why 丁寧な言い方 is correct here.

言い方 means way of saying something, wording, or manner of expression.

So 丁寧な言い方 means something like:

• a polite way of speaking
• polite wording
• a polite manner of expression

It focuses on how the person said it, not just the fact that they said it.

This is slightly more specific than just saying the action was polite. It points to the person’s phrasing or speaking style.

Here, で marks the means or manner of the action.

So 丁寧な言い方で means:

• with a polite way of speaking
• in a polite manner
• using polite wording

It tells you how the person gave the explanation.

You can think of it as similar to with or in in English, depending on the context.

Because the person is not teaching or explaining the meeting room itself. They are explaining where it is.

So the thing being explained is the location:

• 会議室の場所 = the location of the meeting room

Japanese often makes this explicit.

For this meaning, 会議室を教える would usually sound unnatural or incomplete. More natural options are:

• 会議室の場所を教える = tell someone where the meeting room is
• 会議室がどこか教える = tell someone where the meeting room is

So 場所 is there because the information being given is the location.

Because 場所 is the direct object of 教える.

With 教える, the object marked by を is often the thing being taught or told:

• 名前を教える = tell someone a name
• 方法を教える = teach/tell someone the method
• 場所を教える = tell someone the location

So in this sentence, the information that was given is the location, which is why 場所 takes を.

This is 教えて + くれました.

The pattern te-form + くれる means that someone does something for the speaker or for the speaker’s side, often with a nuance of benefit or kindness.

So:

• 教えました = taught / told
• 教えてくれました = kindly told me/us, did me/us the favor of telling

That does not mean it has to sound dramatic. Often it is just a natural Japanese way to show that the action benefited the speaker.

Also:

• くれました is polite past
• so the whole sentence is politely describing a completed action

Japanese often leaves that out when it is obvious from context.

With くれる, the receiver is usually understood to be:

• the speaker
• or someone in the speaker’s in-group

So even without 私に, the sentence naturally suggests that the receptionist told me/us.

If needed, Japanese can make it explicit:

• 受付の人は私に会議室の場所を教えてくれました。

But very often that would be unnecessary.

Yes, you could, and it would sound natural.

There is a small difference in focus:

• 丁寧に教えてくれました

  • means they explained it politely
  • focuses on the action as polite overall

• 丁寧な言い方で教えてくれました

  • means they explained it using polite wording / in a polite way of speaking
  • focuses more specifically on the person’s manner of expression

So both work, but 丁寧な言い方で is a little more descriptive about the style of speech.

Yes, but the viewpoint changes.

Compare these:

• 受付の人は会議室の場所を教えてくれました。

  • focuses on what the receptionist did for me

• 私は受付の人に会議室の場所を教えてもらいました。

  • focuses on me receiving the explanation from the receptionist

Both can describe the same real-world event. The difference is whose perspective the sentence is built around.

So:

• くれる = from the giver’s action toward me/us
• もらう = from my receiving that action

Both are very common in Japanese.
