Questions & Answers about watashi wa ie de shukudai o suru.
は is the topic marker.
In 私 は 家 で 宿題 を する, 私 is not just the grammatical subject; it is the topic – what the sentence is about.
- 私 = I / me
- は = as for / speaking of
So the nuance is: “As for me, (I) do homework at home.”
Key points:
- は does not always mark the grammatical subject; it marks the topic.
- In many sentences, the topic and subject are the same, which is why it often feels like a subject marker to English speakers.
- In natural Japanese, the topic (私) plus は is often omitted when it’s obvious from context.
When は is used as a particle (like in 私は), it is always pronounced “wa”.
When は is part of a word, it is pronounced “ha”:
- Word: 花 (はな) → hana
- Particle: 私 は → watashi wa
This is an orthographic convention that comes from historical Japanese. Today you just memorize:
- Topic particle は → pronounced “wa”
- As part of a normal word → pronounced “ha”
で marks the place where an action happens.
In 家で宿題をする:
- 家 = home / house
- で = at (place where the action is done)
- So: “do homework at home”
Contrast with に:
- に often marks:
- destination: 学校 に 行く → go to school
- location of existence: 家 に いる → be at home
So:
- 家で 宿題をする = do homework at home (action happening there)
- 家に いる = be at home (existence at that place)
- 家に 帰る = go back home (destination)
を is the direct object marker.
In 宿題 を する:
- 宿題 = homework
- を = marks what is being done
- する = do
So 宿題をする literally means “do homework”:
- 宿題 = the thing being acted on
- を = shows “homework” is the object of する
Japanese word order is much more flexible than English, but the verb normally goes at the end.
Basic pattern here:
- [Topic] は [Place] で [Object] を [Verb]
→ 私 は 家 で 宿題 を する
Common variations that are still natural:
- 私 は 宿題 を 家 で する
- 家 で 私 は 宿題 を する (emphasis on at home)
What you cannot do is move the verb to the middle like English:
- ✗ する 私 は 家 で 宿題 を
- ✗ 私は する 宿題 を 家で
So: particles (は, で, を) show each word’s role, which allows some flexibility, but the verb stays at the end.
Yes, you can (and usually would) drop 私 if it is obvious from context.
- 私 は 家で宿題をする。
- 家で宿題をする。 (subject implied as “I” in many contexts)
In Japanese:
- Pronouns like 私, あなた, 彼, 彼女 are omitted a lot when context makes it clear.
- Overusing 私 or あなた can sound unnatural or overly formal / stiff.
In a conversation about your routine, 家で宿題をする alone is perfectly natural as “I do homework at home.”
する is a very common verb meaning “to do”.
It can:
Take a direct object (as here):
- 宿題をする = do homework
- 勉強をする = do (some) studying
- 運動をする = do exercise
Turn many nouns into verbs:
- 勉強 (study) → 勉強する (to study)
- 電話 (telephone) → 電話する (to call)
- 運動 (exercise) → 運動する (to exercise)
So 宿題をする is the standard, neutral way to say “do homework.”
There is also やる, which can sometimes replace する and can sound more casual or rough, but 宿題をする is the safest and most standard form.
Plain する is the non-past form. It can mean:
- habitual / general: I do homework at home (in general)
- future (especially with context): I will do my homework at home (later)
So 私 は 家で 宿題 を する can be understood as:
- “I usually do my homework at home.”
or, in the right context, - “I’ll do my homework at home.”
Other forms:
- した = did (past plain)
- します = do / will do (polite non-past)
- しました = did (polite past)
Example:
- 昨日、家で宿題をした。 = I did my homework at home yesterday.
- 今夜、家で宿題をする。 = I’ll do my homework at home tonight.
Yes, 宿題する is also used, especially in speech.
Patterns:
- 宿題をする – fully explicit, very standard
- 宿題する – natural in casual conversation
In spoken Japanese, を after many direct objects can be omitted, especially with very common combinations like:
- 勉強(を)する
- 宿題(を)する
But you cannot omit the verb する.
So:
- ✓ 宿題をする
- ✓ 宿題する (more casual)
- ✗ 宿題を (incomplete – no verb)
Both can be translated as “home”, but their nuance is different.
家 (いえ)
- Literally “house” (the physical building).
- Can also refer to “home” in a more neutral way.
うち
- More like “home” as a personal space or “my place / our place.”
- Often used when talking about your own home.
In this sentence:
- 家で宿題をする – fine and natural: “do homework at home / at the house.”
- うちで宿題をする – often feels like “do homework at my place / at home,” a bit more personal.
For a beginner, using 家で宿題をする is totally safe and natural.
Japanese often leaves out possessives like my, your, his, her when they are obvious from context.
- English: I do my homework at my house.
- Japanese: 私 は 家で 宿題 を する。
Here, because 私 is the topic:
- It’s automatically understood that 家 is “my house” and 宿題 is “my homework.”
You can say:
- 私 は 私の家で 私の宿題を する。
but that sounds overly repetitive or childish in normal conversation. Only add 私の when you need to contrast or clarify:
- 兄の宿題じゃなくて、私の宿題をする。
→ Not my older brother’s homework, but my homework.
You could say 私が家で宿題をする, but the nuance is different.
私は 家で宿題をする。
- は marks topic: “As for me, I do homework at home.”
- Neutral statement about your routine; very natural.
私が 家で宿題をする。
- が highlights 私 as the one who does it, often with a sense of contrast or focus:
- “I am the one who does homework at home (not someone else).”
- This form is more likely inside a larger sentence, e.g.:
- 私が家で宿題をするのは静かだからだ。
→ The reason I do homework at home is that it’s quiet.
- 私が家で宿題をするのは静かだからだ。
- が highlights 私 as the one who does it, often with a sense of contrast or focus:
For a simple, stand-alone sentence describing your routine, 私は 家で宿題をする is the natural choice.
