Questions & Answers about kare wa tabako o katta.

Why are there spaces between the words? Japanese normally does not use spaces, right?

Yes. In normal Japanese writing, this would usually be written without spaces:

彼はタバコを買った。

Spaces are often added in beginner materials to make the sentence structure easier to see. They help learners identify the parts:

彼 = he
は = topic marker
タバコ = tobacco / cigarettes
を = object marker
買った = bought

What does は do here?

は marks the topic of the sentence.

In 彼はタバコを買った, 彼は means something like as for him or speaking of him.

A very common beginner shortcut is to think of は as marking the subject, and that often works well enough at first. But more precisely, it marks the topic, not always the grammatical subject.

So the sentence is structured like:

彼は = as for him
タバコを = cigarettes/tobacco + object marker
買った = bought

Why is を used after タバコ?

タバコtabako

tobacco; cigarettes

を marks the direct object of the verb.

The direct object is the thing being acted on. In this sentence, the thing being bought is タバコ, so it gets を:

タバコを買った = bought tobacco / bought cigarettes

This is very common in Japanese:

本を読む = read a book
水を飲む = drink water
パンを食べる = eat bread

How is を pronounced? Is it really pronounced wo?

In modern standard Japanese, を is usually pronounced o, not a strong wo sound.

So:

タバコを買った is pronounced roughly tabako o katta

You may still see it romanized as wo because that reflects the traditional kana value and helps show that it is the object marker, but in everyday speech it is basically o.

Why is the verb at the end?

Because Japanese usually follows a subject/topic – object – verb pattern, and the verb commonly comes last.

So instead of English He bought cigarettes, Japanese is:

彼は = he / as for him
タバコを = cigarettes
買った = bought

Putting the verb at the end is one of the most important basic patterns in Japanese.

What form of the verb is 買った?

買った is the plain past form of the verb 買う, which means to buy.

So:

買う = buy / to buy
買った = bought

This form is casual/plain, not polite.

The polite past form would be:

買いました

So:

彼はタバコを買った。 = plain/casual
彼はタバコを買いました。 = polite

Why does 買う become 買った? That seems irregular.

It follows a common conjugation pattern for u-verbs.

買う is a u-verb, and for this type of verb, the plain past is often made by changing the ending to った.

So:

買う → 買った
会う → 会った
使う → 使った

This is a normal pattern, even though it can feel a little surprising at first.

Why is タバコ written in katakana?

Because タバコ is usually written in katakana.

Katakana is often used for:

foreign loanwords
onomatopoeia
emphasis
some words that are conventionally written in katakana

タバコ is one of those words commonly written in katakana. Historically, the word ultimately came from a foreign source, and modern Japanese normally writes it this way.

Does タバコ mean one cigarette or cigarettes in general?

Japanese nouns usually do not change form for singular vs. plural.

So タバコ can mean:

cigarette
cigarettes
tobacco

The exact meaning depends on context.

In many everyday contexts, タバコを買った would naturally be understood as bought cigarettes, but the noun itself does not have a plural ending like English -s.

Why is there no word for a, the, or some?

Japanese does not have articles like English a and the.

That means a noun like タバコ can be understood in different ways depending on context:

a cigarette
the cigarettes
some cigarettes
tobacco

Japanese often leaves this unspecified unless it is important to be precise.

Does 彼 always just mean he?

Not always.

彼 can mean he, but in real Japanese it can also sometimes mean boyfriend, depending on context.

However, in a simple sentence like this, learners should usually read 彼 as he.

Also, native speakers often omit pronouns entirely when the meaning is clear, so Japanese does not use 彼 as constantly as English uses he.

Could this sentence be said without 彼は?

Yes, very often.

Japanese frequently omits information that is understood from context. So if everyone already knows who the person is, you could simply say:

タバコを買った。

That would still mean something like (He/I/someone) bought cigarettes, depending on context.

This is very natural in Japanese. Pronouns are often left out when they are not needed.

What is the difference between は and が here? Could it be 彼がタバコを買った?

Yes, 彼がタバコを買った is also possible, but the nuance changes.

Very roughly:

彼はタバコを買った = As for him, he bought cigarettes
彼がタバコを買った = He is the one who bought cigarettes

So:

は presents 彼 as the topic
が gives stronger focus to 彼 as the subject

If you are simply talking about him, は is natural. If you are identifying who bought the cigarettes, が may be more natural.

Is this sentence casual?

Yes. It uses the plain form 買った, so it is casual/plain in style.

That does not automatically mean rude. Plain form is normal:

with friends
in casual conversation
in diaries
in stories
in informal writing

If you want to sound polite, use:

彼はタバコを買いました。

How would this sound in natural speech? Is 彼は a little stiff?

It can be, depending on context.

In actual conversation, Japanese often prefers to omit the pronoun if it is obvious. So a more natural spoken sentence might simply be:

タバコを買った。

Using 彼は is not wrong, but it can sound more explicit than English he sometimes does. Japanese speakers do not always keep repeating pronouns the way English speakers do.

What exactly is the role of each part in the sentence?

A useful breakdown is:

彼 — noun/pronoun: he
は — topic marker
タバコ — noun: tobacco / cigarettes
を — direct object marker
買った — verb, plain past of 買う: bought

So the structure is:

[topic] + [object] + [verb]

which is a very common Japanese sentence pattern.
