kare ha watasi no hikkosi wo tetudatte kuremasita.

手伝ってくれました is 手伝う in the -te form plus くれました.

• 手伝う = to help
• 手伝って = helping / help and...
• くれました = gave (to me / to us), but after a -te form it means did something for me/us

So 手伝ってくれました means:

• he helped me
• more literally: he did the favor of helping me

If you said 手伝いました, that would simply mean helped, without the extra nuance that the action was done for the speaker’s benefit.

These verbs describe giving from different viewpoints.

• 〜てくれました = someone did something for me/us
• 〜てもらいました = I received the favor of someone doing something
• 〜てあげました = I did something for someone else

So:

• 彼は私の引っ越しを手伝ってくれました。
  = He helped me with my move.
• 私は彼に引っ越しを手伝ってもらいました。
  = I had him help me with my move / I received his help.

They describe roughly the same event, but from different perspectives.

は marks 彼 as the topic of the sentence.

So 彼は means something like:

• as for him
• he

In natural English, we usually just say he, but in Japanese は shows what the sentence is about.

の connects nouns. Here it shows that the move belongs to or is associated with me.

• 私 = I / me
• 私の = my
• 引っ越し = moving / a move

So 私の引っ越し means:

• my move
• my moving

It does not mean that I moved him. It means the move was mine.

を marks the direct object of the verb.

The verb 手伝う usually takes the thing being helped with as its object:

• 仕事を手伝う = help with the work
• 宿題を手伝う = help with homework
• 引っ越しを手伝う = help with the move

So 私の引っ越しを手伝う literally means help my move.

In natural English, we often say help with my move, but Japanese uses を with 手伝う.

The -te form is needed before くれる in this grammar pattern.

Pattern:

• verb in -te form + くれる
• meaning: someone does something for me/us

So:

• 手伝う → 手伝って
• 手伝ってくれる = someone helps me / does me the favor of helping
• 手伝ってくれました = someone helped me (polite, past)

This is a very common pattern in Japanese.

くれました is:

• past tense
• polite style

Breakdown:

• くれる = plain non-past
• くれます = polite non-past
• くれました = polite past

So the sentence is politely saying that the helping happened in the past.

Yes, very often.

Japanese frequently leaves out information that is obvious from context. Since 〜てくれました already strongly suggests the action was done for the speaker or the speaker’s in-group, 私 is often unnecessary.

So a very natural version is:

• 彼は引っ越しを手伝ってくれました。

This still usually means He helped me with my move, if the context makes that clear.

Including 私の adds emphasis or clarity.

It is grammatically correct, but in real conversation Japanese often avoids pronouns when the person is already clear from context.

So instead of 彼は, people might simply say:

• 引っ越しを手伝ってくれました。
• or use the person’s name:
  • 田中さんは私の引っ越しを手伝ってくれました。

Frequent use of he and she in English does not always match natural Japanese usage.

引っ越し is read ひっこし.

It comes from the verb 引っ越す（ひっこす）, meaning to move house.

The small っ shows a doubled consonant sound, so:

• ひこし would be wrong
• ひっこし is correct

This word can mean:

• moving
• a move
• relocation

No. In this sentence, 引っ越し is functioning as a noun.

Even though it is related to the verb 引っ越す, the -ます stem can often act like a noun in Japanese.

So:

• 引っ越す = to move
• 引っ越し = moving / a move

That is why it can be followed by の and を like a noun.

Yes, but the nuance changes.

• 彼は makes him the topic: As for him, he helped me with my move.
• 彼が marks him as the specific subject and can sound more like:
  • He is the one who helped me with my move
  • or it may answer a question like Who helped you?

So both are possible, but は and が are not always interchangeable.

Yes. The pattern 〜てくれる often carries a feeling that the speaker appreciates the action, because it presents the action as a favor done for the speaker’s benefit.

So 彼は私の引っ越しを手伝ってくれました is not just a cold statement of fact. It can naturally suggest:

• He kindly helped me with my move
• He helped me out with my move

The gratitude is subtle, but it is often there.
