When you want to say that you did something "alone" or "by yourself" in Japanese, you can use 一人で (hitori de). The 一人 (hitori) part means "one person," and the で (de) particle indicates the means or method, so it literally translates to "by one person."
For example, if you ate dinner alone, you would say: 一人で晩ご飯を食べました (Hitori de bangohan o tabemashita). It's a very common phrase to use when you want to emphasize that no one else was with you when you performed an action.
When you want to express that someone is doing something 'alone' or 'by themselves' in Japanese, the word you're looking for is 一人で (hitori de).
This adverb combines 一人 (hitori), meaning 'one person,' with the particle で (de), which indicates the means or method by which an action is performed.
So, literally translated, it's like saying 'by one person' or 'with one person,' but it effectively conveys the idea of being solitary in an action.
You'll find this phrase useful in many everyday situations, whether you're talking about eating alone, studying by yourself, or traveling without company.
When you want to express that someone is doing something 'alone' or 'by themselves' in Japanese, you use the adverb 一人で (hitori de). This literally translates to 'by one person'. The 'で' particle here indicates the means or method, so it's like saying 'by means of one person'.
For instance, if you want to say 'I live alone,' you would say 私は一人で住んでいます (Watashi wa hitori de sunde imasu). Or, if you did something without help, you could say 私はこのプロジェクトを一人でやりました (Watashi wa kono purojekuto o hitori de yarimashita), meaning 'I did this project by myself.'
It's a versatile phrase that you'll encounter often, so practicing its usage can greatly enhance your ability to describe solitary actions or states.
When using 「一人で」(hitori de), the 「で」(de) particle indicates the means or way in which an action is performed. So, 「一人で」literally means “by means of one person” or “with one person,” which translates to “alone” or “by oneself.”
It can describe doing something without assistance, or simply being physically alone. For example, you might say 「一人で勉強します」(hitori de benkyō shimasu) to mean "I study alone," emphasizing that you're doing the studying by yourself.
Or, if you’re asking someone if they went to a place without company, you could ask 「一人で行きましたか」(hitori de ikimashita ka)? meaning "Did you go alone?"

容易混淆的词
だけ means 'only' or 'just.' While you might say '私だけ' (only me), it doesn't carry the sense of doing something 'by oneself' or 'unaccompanied' like 一人で does.
単独で also means 'alone' or 'independently,' but it sounds more formal and is often used in official or technical contexts, like '単独行動' (acting independently) or '単独飛行' (solo flight). 一人で is more common for everyday actions.
This means 'by myself' or 'on my own,' emphasizing personal effort. While similar, 一人で focuses on the state of being unaccompanied, whereas 自分自身で emphasizes the action being done without help from others, often implying capability.
容易混淆
This is an alternate spelling of 一人で, meaning 'alone' or 'by oneself.' While both are correct, 一人で is more common in everyday writing. The kanji 独 emphasizes solitude.
Essentially the same meaning as 一人で. The choice often comes down to nuance or personal preference in writing. Think of 独りで as emphasizing the 'single' or 'solitary' aspect more strongly.
独りで映画を見た。(I watched a movie alone.)
Sounds similar to 一人で but means 'one by one' or 'individually.' It describes a sequential action for multiple people.
一人で refers to a single person doing something by themselves. 一人ずつ refers to multiple people performing an action in sequence.
一人ずつ部屋に入ってください。(Please enter the room one by one.)
This word refers to an 'only child.' While it contains 一人, the meaning is very specific and unrelated to doing something 'alone.'
一人で describes an action. 一人っ子 describes a familial status.
彼女は一人っ子です。(She is an only child.)
This means 'solo travel' or 'traveling alone.' It's a specific type of activity done alone, not the general state of being alone.
一人で is a general adverb for 'alone.' 一人旅 is a specific noun referring to a type of trip.
私は一人旅が好きです。(I like solo travel.)
This is a more casual, sometimes negative, slang term for being 'alone' or 'lonely,' especially in the context of being isolated or having no friends.
一人で is neutral and simply states the fact of being alone. ぼっち carries a connotation of loneliness or social exclusion, often used by younger generations.
彼はいつもぼっちでいる。(He is always alone/a loner.)

Which of the following sentences correctly uses 「一人で」?

Choose the sentence where 一人で is used correctly.
一人で means 'alone' or 'by oneself'. The sentence '彼女は一人で旅行するのが好きです。' (She likes to travel alone.) uses it correctly. The others imply doing something alone with others, which is contradictory.
Which sentence best expresses the idea of doing something 'without help'?
While all options involve 'alone', '彼らは一人でパーティーの準備をしました。' (They prepared for the party by themselves.) strongly implies completing a task without assistance, which is a common nuance of 一人で.
Select the most natural English translation for: 「彼は一人で問題を解決した。」
Both 'alone' and 'by himself' are good translations, but 'by himself' often carries the nuance of accomplishing something without assistance, which fits the context of solving a problem.
The sentence 「私は一人で買い物に行った。」 implies that I went shopping with someone else.
「一人で」 explicitly means 'alone' or 'by oneself', so it implies the opposite – that I went shopping without anyone else.
Using 「一人で」 suggests independence or self-sufficiency.
Yes, '一人で' often implies the ability to do things without relying on others, hence suggesting independence or self-sufficiency.
「一人で」 can only be used when referring to a single person.
While it literally contains '一人' (one person), it can be used for a group who collectively act 'by themselves' without outside help, as in 「彼らは一人でパーティーの準備をしました。」 (They prepared for the party by themselves.)

Select the sentence where '一人で' is used correctly:
'一人で' refers to a single person acting independently. In the other options, the plural subjects ('彼ら', '私達', 'あなた') are grammatically incorrect with '一人で'.

The phrase '一人で諦めなかった' implies he didn't give up even when facing difficulties alone, emphasizing his resilience. The other options don't fit the context as well.
The sentence '彼女は一人で新しいプロジェクトを成功させた。' means 'She succeeded in the new project by herself.'
'一人で' directly translates to 'by herself' or 'alone', indicating that she independently achieved success in the new project.
It is grammatically correct to say '私たちは一人で映画を見に行った。'
'私たち' (we) is plural, while '一人で' (alone; by oneself) refers to a single individual. The correct phrasing would be '私たちはみんなで映画を見に行った。' (We all went to see a movie.) or '私たちはそれぞれ一人で映画を見に行った。' (We each went to see a movie by ourselves.).
When someone says '彼はいつも一人でいることを好む。', it implies that he likes being alone.
