は marks 彼女 as the topic of the sentence.

That means the sentence is talking about her, and what follows is information about her situation and what she said. Once 彼女は sets the topic, Japanese can leave she unstated in the rest of the sentence, even though she is still the understood subject of 行く, 会っておきたい, and 言っていた.

しばらく means for a while or for some time.

It is intentionally vague. It does not tell you exactly how long she will be abroad; it just suggests that it will not be very brief. In this sentence, it modifies the idea of going abroad, so the feeling is:

• she will be away
• for a while
• long enough that it affects when she can meet her friends

Yes, 海外へ行く would also be possible.

In this sentence, に marks the destination of movement: go abroad. With verbs of motion like 行く, both に and へ can often be used.

Very roughly:

• に focuses more on the destination
• へ focuses a bit more on the direction toward that destination

In everyday use, both are common, and the difference here is small.

Also, 海外 by itself means overseas / abroad. It behaves like a noun here.

Both ので and から can mean because / since, but ので usually sounds a bit softer and more explanatory.

Here, 海外に行くので gives the reason in a natural, less blunt way:

• she is going abroad for a while,
• so she wants to meet her friends while she still can.

Compared with から, ので often feels:

• more objective
• more gentle
• more suitable for explanations

So it fits well in reported speech like this.

Because the point is while she is still able to meet them.

会える is the potential form of 会う, so it means can meet or be able to meet.
Then うちに means while... or during the period when....

So 友達と会えるうちに means:

• while she still has the chance to meet her friends
• before that opportunity disappears

If you said 会ううちに, that would be a different structure and meaning, more like while meeting or in the course of meeting, which is not what this sentence wants.

Here, うちに means while it is still the case that... or before the situation changes.

So 会えるうちに means:

• while she can still meet them
• before she leaves and it becomes difficult or impossible

This is a very common use of うちに. It often carries the idea of taking action before an opportunity ends.

Examples of the same pattern:

• 温かいうちに食べてください = Please eat it while it’s still warm.
• 若いうちに勉強したほうがいい = It’s better to study while you’re still young.

Both can be possible, but they give slightly different feelings.

With 会う / 会える:

• に can mark the person you meet
• と can emphasize meeting with someone, especially in a more mutual or social sense

So 友達と会える feels very natural for be able to meet up with friends.

Very roughly:

• 友達に会える = can meet my friends
• 友達と会える = can meet up with my friends / can get together with my friends

The difference is small here, and both are understandable.

何度も means many times, repeatedly, or again and again.

It comes before the verb phrase it modifies:

• 何度も会っておきたい = want to meet many times / want to meet repeatedly

Japanese adverbs often appear before the verb they modify, so this placement is normal.

This is one of the most important parts of the sentence.

会いたい simply means want to meet.

But 会っておきたい adds 〜ておく, which often means:

• do something in advance
• do something beforehand
• do something while you have the chance

So 何度も会っておきたい means something like:

• I want to meet them many times before I go
• I want to make sure I meet them while I still can

It has a preparatory or opportunity-based nuance. She is not just expressing a desire to meet; she wants to do it before the upcoming change of going abroad.

Because 〜ておく attaches to the て-form of a verb.

The base verb is 会う. Its て-form is 会って. Then you add おく:

• 会う
• 会って
• 会っておく
• 会っておきたい

So grammatically, this is:

• 会っておく = to meet in advance / to meet while one has the chance
• 会っておきたい = want to meet in advance / want to meet while one still can

In casual speech, 〜ておく is often contracted:

• 会っとく
• 会っときたい

But the sentence you were given uses the standard form.

This と marks the content of what was said.

So everything before と is the thing she was saying:

• 友達と会えるうちに何度も会っておきたい
• と言っていた = was saying that...

This is a very common pattern in Japanese:

• clause + と
  • 言う

It can be used for direct quotes, indirect quotes, thoughts, and reported speech.

言っていた often gives the sense of:

• was saying
• had said
• used to say
• was in the state of having said

In reported speech, 〜と言っていた is extremely common. It often sounds more natural than a simple 言った when you are recounting what someone said earlier.

Possible nuances of 言っていた here:

• she said this earlier, and the speaker is reporting it now
• she may have said it more than once
• the speaker is recalling her previously stated intention

By contrast, 言った would sound more like a simple one-time event: she said.

It is still 彼女.

Japanese often omits subjects once they are understood from context. Since the sentence starts with 彼女は, the default reading is that she is the one who:

• will go abroad
• wants to meet friends many times before that
• was saying this

So even though she is not repeated, it is still the same person throughout the sentence.

It breaks down like this:

• 彼女は = as for her
• しばらく海外に行くので = since she is going abroad for a while
• 友達と会えるうちに = while she can still meet her friends
• 何度も会っておきたい = she wants to meet them many times beforehand / while she has the chance
• と言っていた = she was saying

So the sentence has:

1. a topic
2. a reason clause
3. a time/opportunity clause
4. the main content of what she said
5. the reporting verb

This kind of long clause-chaining is very normal in Japanese.

The comma is helpful, but it is not a special grammatical requirement in the same way as a particle.

It simply makes the sentence easier to read by showing a pause after the reason clause:

• しばらく海外に行くので、
• then the rest of the sentence

Japanese commas often reflect readability, rhythm, or the writer’s choice. So the sentence could still be understood without that comma, but the comma makes the structure clearer.
