前 is a noun, so when you say before X, you usually connect X to 前 with の.

• 旅行の前に = before the trip
• literally: trip + of + front/before + at

The final に marks the time point before which something happens.

Compare:

• 授業の前に = before class
• 寝る前に = before sleeping

Notice that with a verb, you do not use の:

• 寝る前に = before sleeping
• not 寝るの前に

には is に + は.

In this sentence, に marks the person the speaker wants to do the action, and は adds a topic/contrast nuance.

So:

• 弟に = to/for my younger brother
• 弟には = as for my younger brother / at least my younger brother / my younger brother, specifically

The は often suggests contrast, even if only lightly. For example, it can imply something like:

• As for my younger brother, I want him to put away the laundry early.
• maybe compared with other people, or just highlighting him

Without は, the sentence would still be natural:

• 旅行の前に弟に洗濯物を早めに片付けてほしい。

That version is a little more neutral.

In the pattern A に B を V-てほしい, に marks the person you want to do the action.

So here:

• 弟に = my younger brother is the person the speaker wants to act
• 洗濯物を片付けてほしい = want someone to put away the laundry

This is a very common pattern:

• 友達に来てほしい。 = I want my friend to come.
• 母に見てほしい。 = I want my mother to look at it.

So に here does not mean destination. It marks the person from whom the speaker wants the action.

Because ほしい can combine with the て-form to mean:

I want someone to do X.

Pattern:

• V-てほしい

So:

• 片付けてほしい = I want someone to put it away / tidy it up

By contrast:

• ほしい after a noun means want a thing
  • お金がほしい。 = I want money.
• たい means want to do something yourself
  • 片付けたい。 = I want to put it away.

So:

• 片付けたい = I want to tidy it up.
• 片付けてほしい = I want someone else to tidy it up.

That is the key difference.

It expresses the speaker’s desire.

So the sentence means that the speaker wants their younger brother to put away the laundry early before the trip.

It does not mean:

• my younger brother wants to put away the laundry

If you wanted to say that the younger brother wants to do it, you would use something like:

• 弟は洗濯物を早めに片付けたい。

So in V-てほしい, the hidden subject of ほしい is usually the speaker, or the person whose feelings are being described in context.

早めに means a bit early, rather early, or earlier than usual / earlier than might be expected.

It comes from:

• 早い = early
• 早め = early side / somewhat early
• 早めに = early / sooner rather than later

So 早めに片付けてほしい means something like:

• I want him to put it away fairly early
• I want him to do it ahead of time
• I want him to do it sooner rather than later

This is softer and more flexible than a strict time expression.

Both can mean early, but the nuance is a little different.

• 早く = early / quickly
• 早めに = a little early / on the early side / in advance

So:

• 早く片付けてほしい。
  can sound like I want you to do it soon / quickly
• 早めに片付けてほしい。
  sounds more like I want you to get it done ahead of time

In this sentence, 早めに fits well because there is a deadline-like context: before the trip.

No. Here 片付ける means put away, tidy up, or clear away the laundry.

• 洗濯する = wash clothes / do laundry
• 片付ける = put things in order, tidy up, put away

So 洗濯物を片付ける usually means something like:

• fold and put away the clean clothes
• clear the laundry away instead of leaving it lying around

It is about organizing/putting away, not the washing itself.

Because 洗濯物 is the direct object of 片付ける.

• 洗濯物を片付ける = put away the laundry

The thing being acted on gets を.

So the structure is:

• 弟には = as for my younger brother
• 洗濯物を = the laundry
• 早めに片付けてほしい = I want him to put it away early

Yes, very likely.

Japanese often leaves out subjects and topics when they are understood from context. A natural fuller version could be:

• 私は旅行の前に弟には洗濯物を早めに片付けてほしい。

But Japanese normally drops 私は if it is already obvious.

So even though I is not stated, the sentence naturally sounds like:

• I want my younger brother to put away the laundry early before the trip.

Yes, at least a little.

The は in 弟には can suggest contrast such as:

• As for my younger brother, I want him to do it
• maybe other people are a different case
• or the speaker is singling him out for emphasis

Sometimes the contrast is strong, sometimes very light. Japanese often uses は even when the contrast is only implied rather than stated.

For example, it could suggest something like:

• I am not saying this about everyone, but my younger brother should do it early.

If you remove は, that contrastive feeling becomes weaker.

It expresses the speaker’s desire, and depending on context it can function like a request.

• 片付けてほしい。 = I want you/him to put it away.

This is usually less direct than an imperative like:

• 片付けろ。 = Put it away.

But if said directly to someone, ～てほしい can still sound firm, because you are clearly stating what you want them to do.

If the speaker wants to sound softer, they might say:

• 片付けてほしいんだけど。
• 早めに片付けてくれる？
• 早めに片付けてもらえる？

So ～てほしい is not rude by itself, but it is a fairly direct statement of desire.

Yes. Japanese word order is flexible as long as the particles stay clear.

For example, these are all possible with only slight differences in emphasis:

• 旅行の前に弟には洗濯物を早めに片付けてほしい。
• 弟には旅行の前に洗濯物を早めに片付けてほしい。
• 洗濯物を弟には旅行の前に早めに片付けてほしい。

The original order is natural because it sets the time frame first:

• before the trip
• as for my younger brother
• the laundry
• early
• I want him to put it away

So the sentence flows in a very understandable way.
