annaizyo no hito ha, tikaku no hunsui made no miti mo osiete kuremasita.

Because の is doing its very common job of linking one thing to another.

In this sentence, it appears three times:

• 案内所の人 = the person of / at the information desk
• 近くの噴水 = the nearby fountain
• 噴水までの道 = the road/path to the fountain

So の is not always translated the same way. It often works like:

• of
• at
• to
• an English adjective-like connector

A useful way to think of it is: の connects a modifier to a noun.

案内所 means information desk / information center / information booth, and 人 means person.

So 案内所の人 literally means the person of the information desk, but in natural English it means:

• the person at the information desk
• the staff member at the information desk

Japanese often uses Noun + の + 人 to mean a person associated with that place or thing.

は marks the topic of the sentence.

So 案内所の人は means something like:

• As for the person at the information desk...
• The person at the information desk...

It sets up who we are talking about. The rest of the sentence tells what that person did.

A very rough structure is:

• 案内所の人は = topic
• 近くの噴水までの道も = thing that was also explained
• 教えてくれました = explained/told me

近く means nearby area / vicinity / near. When followed by の, it can modify a noun.

So:

• 近くの噴水 = the nearby fountain

This is a very common pattern:

• 近くの店 = a nearby store
• 駅の近くのホテル = a hotel near the station

Here, 近く is acting like something that describes 噴水.

まで means up to / until / as far as and marks an endpoint.

So:

• 噴水まで = to the fountain
• 噴水までの道 = the road/path to the fountain

The の lets the whole phrase 噴水まで modify 道.

So the pattern is:

• Place までの 道 = the road/path/way to a place

Examples:

• 駅までの道 = the way to the station
• 学校までの道 = the road to school

Here, 道 does not necessarily mean one physical road only. It often means the way / route / directions.

道 literally means road or path, but in many contexts it also means the way or route to get somewhere.

In this sentence, 噴水までの道 is best understood as:

• the way to the fountain
• the route to the fountain
• directions to the fountain

So even though the literal word is road/path, the natural meaning is broader.

も means also or too.

So 近くの噴水までの道も means:

• also the way to the nearby fountain
• the directions to the nearby fountain as well

This implies that the person at the information desk had already told the speaker something else too.

For example, the earlier context might be:

• they explained where a building was
• and also told the speaker how to get to the fountain

So も adds a sense of in addition.

This is a very common learner question.

• 教えました = taught / told
• 教えてくれました = taught / told for my benefit

The くれる part adds the nuance that someone did something kindly for the speaker or the speaker’s in-group.

So 教えてくれました suggests:

• the person helped me by telling me
• they did me the favor of explaining it

In English, we often do not translate this explicitly, but the nuance is there in Japanese.

Japanese often leaves out things that are understood from context.

In 教えてくれました, the receiver is usually the speaker or someone close to the speaker. So even though me is not stated, it is understood.

So the sentence naturally implies:

• The person at the information desk also told me the way to the nearby fountain.

This omission is very normal in Japanese.

Yes. 教える can mean:

• teach
• tell
• inform
• show someone how

In the context of places or directions, it often means:

• tell someone
• show someone
• give directions

So here, 道を教える means:

• tell someone the way
• give directions

It does not necessarily mean formal teaching like in a classroom.

A simple breakdown is:

• 案内所の人は = the person at the information desk
• 近くの噴水までの道も = also the way to the nearby fountain
• 教えてくれました = told me / explained for my benefit

So the overall pattern is:

• Topic + thing explained + verb

Japanese puts the verb at the end, so the sentence builds up modifiers before you get to the action.

Yes, that is a very natural translation.

Even though the literal pieces are closer to:

• The person at the information desk also told me the road/path to the nearby fountain

natural English would often say:

• The person at the information desk also gave me directions to the nearby fountain.

That captures the meaning and the function of 道を教える very well.

The comma is mostly a writing choice to make the sentence easier to read.

It shows a pause after the topic:

• 案内所の人は、

Japanese often uses commas to separate long topics or make nested phrases clearer. Since this sentence has a fairly long noun phrase in the middle, the comma helps readability.

It is not changing the grammar in a major way.
