Guide to Japanese

Compound Sentences

In this section, we will learn various ways to combine multiple simple sentences into one complex sentence. For example, we will learn how to chain separate sentences together to express multiple actions or states. In other words, if we have two simple sentences with the same subject, “I ran” and “I ate”, we will learn how to group them together to mean, “I ran and ate.” We will also learn how to do this with adjectives and nouns. (Ex: He is rich, handsome, and charming.)

Expressing a sequence of states

魅力的(み・りょく・てき)
charming

It is very easy to combine a chain of nouns and adjectives to describe a person or object. For example, in English if we wanted to say, “He is X. He is Y. He is Z.” since all three sentences have the same noun, we would usually say, “He is X, Y, and Z.” In Japanese, we can do the same thing by conjugating the noun or adjective. The last noun or adjective remains the same as before.

How to chain nouns and adjectives together

For nouns and na-adjectives: Attach to the noun or na-adjective.

Examples

  1. 一般的 → 一般的
  2. 静か → 静か

For i-adjectives and negative noun/adjectives: Replace the with くて.

(For いい and かっこいい, the い→よ exception applies here as well.)

Examples

  1. → 狭くて
  2. 彼女じゃな → 彼女じゃなくて
  3. いいよくて

Examples

  1. 私の部屋は、きれい、静か、とても好き。
    My room is clean, quiet, and I like it a lot.

  2. 彼女は、学生じゃなくて、先生だ。
    She is not a student, she is a teacher.

  3. 田中さんは、お金持ち、かっこよくて、魅力的ですね。
    Tanaka-san is rich, handsome, and charming, isn’t he?

As you can see, the attached to お金持ち obviously cannot be the context particle here because there is no verb. It might be helpful to think of as merely a substitution for that can be chained together.

Expressing a sequence of verbs with the te-form

In a similar fashion, you can express multiple actions. It is usually interpreted as a sequence of event. (I did [X], then I did [Y], then I finally did [Z].) There are two forms: positive and negative. The tense of all the actions is determined by the tense of the last verb.

How to chain verbs together

Positive: Conjugate the verb to its past tense and replace with or with . This is often called the te-form even though it could sometimes be ‘de’.

Negative: Same as i-adjectives, replace with くて. This rule also works for the polite です and ます endings.

Examples

  1. 学生で → 学生でし → 学生でし
  2. 買いま → 買いまし → 買いまし

You can connect two complete sentences using から to indicate a reason for something. The two sentences are always ordered [reason] から [result]. When the reason is a non-conjugated noun or na-adjective, you must add to explicitly declare the reason in the form of ""(noun/na-adjective)から. If you forget to add the declarative ""だ to から, it will end up sounding like the から meaning “from” which was first introduced in the section on particles, earlier.

Examples

  1. 時間がなかったからパーティーに行きませんでした。
    There was no time so didn’t go to party.

  2. 友達からプレゼントが来た。
    Present came from friend.

  3. 友達だからプレゼントが来た。
    Present came because (the person is) friend. (This sentence sounds a bit odd.)

Either the reason or the result can be omitted if it is clear from the context. In the case of polite speech, you would treat から just like a regular noun and add です.

Example 1

田中(た・なか)さん Tanaka-san
どうしてパーティーに行きませんでしたか。
Why didn’t you go to the party?
山田(や・まだ)さん Yamada-san
時間がなかったからです。
It’s because I didn’t have time.

Example 2

一郎(いち・ろう) Ichiro
パーティーに行かなかったの?
You didn’t go to the party?
直子(なお・こ) Naoko
うん、時間がなかったから
Yeah, because I didn’t have time.

Example 3

When you omit the reason, you must include the declarative or です.

直子(なお・こ) Naoko
時間がなかった。
I didn’t have time.
一郎(いち・ろう) Ichiro
だからパーティーに行かなかったの?
Is that why you didn’t go to the party?

Notice that we could have also used the explanatory to express the same thing. In other words, 山田さん could have also said, 時間がなかったのです or 時間がなかったんです while 直子 could have said 時間がなかったの (we’ll assume she wants to use the more feminine form).

In fact, this is where ので possibly came from. Let’s say you want to combine two sentences: 時間がなかったのだ and パーティーに行かなかった. Remember we can treat the just like a noun so we can use what we just learned in the first section of this lesson. 時間がなかったのだ+パーティーに行かなかった becomes: 時間がなかったのでパーティーに行かなかった。 In fact, ので is almost interchangeable with から with a few subtle differences. から explicitly states that the sentence preceding is the reason for something while ので is merely putting two sentences together, the first with an explanatory tone.

This is something I call causation where [X] happened, therefore [Y] happened. This is slightly different from から where [Y] happened explicitly because [X] happened. This difference tends to make ので sound softer and slightly more polite and it is favored over から when explaining a reason for doing something that is considered discourteous.

  • ちょっと忙しいので、そろそろ失礼します。
    Because I’m a little busy, I’ll be making my leave soon.

失礼します, which literally means “I’m doing a discourtesy”, is commonly used as a polite way to make your leave or disturb someone’s time.)

Reminder:

Don’t forget that the explanatory requires a for both non-conjugated nouns and na-adjectives. Review Particles 3 to see why.

  1. 私は学生ので、お金がないんです。
    Because I’m a student, I have no money (lit: there is no money).

  2. ここは静かので、とても穏やかです。
    It is very calm here because it is quiet.

  3. ので、友達に会う時間がない。
    That’s why there’s no time to meet friend.

Just like how the explanatory can be shortened to , in speech, the ので can be changed to んで simply because it’s easier to slur the sounds together rather than pronouncing the / o / syllable.

  1. 時間がなかったんでパーティーに行かなかった。
    Didn’t go to the party because there was no time.

  2. ここは静かなんで、とても穏やかです。
    It is very calm here because it is quiet.

  3. なんで、友達に会う時間がない。
    That’s why there’s no time to meet friend.

Using のに to mean “despite”

Vocabulary

毎日(まい・にち)
everyday
運動(うん・どう)
exercise
する exception
to do
全然(ぜん・ぜん)
not at all (when used with negative)
痩せる(や・せる) ru-verb
to become thin
学生(がく・せい)
student
彼女(かの・じょ)
she; girlfriend
勉強(べん・きょう)
study

Grammatically, のに is used exactly the same way as ので. When used to combine two simple sentences together, it means “[Sentence 1] despite the fact that [Sentence 2].” However the order is reversed: [Sentence 2]のに[Sentence 1].

Examples

  1. 毎日運動したのに、全然痩せなかった。
    Despite exercising every day, I didn’t get thinner.

  2. 学生なのに、彼女は勉強しない。
    Despite being a student, she does not study.

Expressing contradiction using and けど

Vocabulary

デパート(de pa a to)
department store
行く(い・く) u-verb
to go
(なに/なん)
what
全然(ぜん・ぜん)
not at all (when used with negative)
欲しい(ほ・しい) i-adj
desirable
友達(とも・だち)
friend
聞く(き・く) u-verb
to ask; to listen
知る(し・る) u-verb
to know
今日(きょう)
today
(ひま)
free (as in not busy)
明日(あした)
tomorrow
忙しい(いそが・しい) i-adj
busy
(かれ)
he; boyfriend
まだ
yet
好き(す・き) na-adj
likable; desirable
いい i-adj
good
(もの)
object
たくさん
a lot (amount)
ある
to exist (inanimate)
見る(み・る) ru-verb
to see
面白い(おも・しろ・い) i-adj
interesting

Used in the same manner as から and ので, and けど also connect two sentences together but this time to express a contradiction. Just like から the declarative is required for nouns and na-adjectives. And just like から and ので, either part of the contradiction can be left out.

Examples

  1. デパートに行きました、何も欲しくなかったです。
    I went to department store but there was nothing I wanted.

  2. 友達に聞いたけど、知らなかった。
    I asked (or heard from) a friend but he (or I) didn’t know.

  3. 今日は暇だけど、明日は忙しい。
    I’m free today but I will be busy tomorrow.

  4. だけど、彼がまだ好きなの。
    That may be so, but it is that I still like him. [explanation, feminine tone]

It may seem odd but 聞く can either mean “to listen” or “to ask”. You may think this may become confusing but the meaning is usually clear within context. In the second example, we’re assuming that the friend didn’t know, so the speaker was probably asking the friend.

Yet again we see the importance of context in Japanese because this sentence can also mean, “I heard from a friend but I didn’t know” since there is neither subject nor topic. Similar to the difference between ので and から, has a softer tone and is slightly more polite than けど.

Though this isn’t a rule as such, it is generally common to see attached to a ~ます or ~です ending and けど attached to a regular, plain ending. A more formal version of けど is けれど and even more formal is けれども, which we may see later when we cover formal expressions.

Unlike the English word for contradiction such as “but” or “however”, けど and do not always express a direct contradiction. Often times, especially when introducing a new topic, it is used as a general connector of two separate sentences.

For example, in the following sentences, there is no actual contradiction but and けど are used simply to connect the sentences. Sometimes, the English “and” becomes a closer translation than “but”.

  1. デパートに行きました、いい物がたくさんありました。
    I went to the department store and there was a lot of good stuff.

  2. マトリックスを見たけど、面白かった。
    I watched the “Matrix” and it was interesting.

Expressing multiple reasons using

Vocabulary

どうして
why
友達(とも・だち)
friend
先生(せん・せい)
teacher
年上(とし・うえ)
older
(かれ)
he; boyfriend
好き(す・き) na-adj
likable
優しい(やさ・しい) i-adj
gentle; kind
かっこいい i-adj
cool; handsome
面白い(おも・し・ろい) i-adj
interesting

When you want to list reasons for multiple states or actions you can do so by adding to the end of each relative clause. It is very similar to the particle except that it lists reasons for verbs and state-of-being. Again, for states of being, must be used to explicitly declare the state-of-being for any non-conjugated noun or na-adjective. Let’s look at some examples.

Example 1

? : どうして友達じゃないんですか?
Why isn’t (he/she) friend [seeking explanation]?
先生だし、年上だし・・・。
Well, he’s/she’s the teacher, and older…

Example 2

どうして彼が好きなの?
Why (do you) like him?
優しい、かっこいい、面白いから。
Because he’s kind, attractive, and interesting (among other things).

Notice that 優しくて、かっこよくて、面白いから。 could also have worked but much like the difference between the and particle, implies that there may be other reasons.

Expressing multiple actions or states using ~たりする

Vocabulary

する exception
to do
食べる(た・べる) ru-verb
to eat
飲む(の・む) u-verb
to drink
簡単(かん・たん) na-adj
simple
難しい(むずか・しい) i-adj
difficult
映画(えい・が)
movie
見る(み・る) ru-verb
to see
(ほん)
book
読む(よ・む) u-verb
to read
昼寝(ひる・ね)
afternoon nap
この
this (abbr. of これの)
大学(だい・がく)
college
授業(じゅ・ぎょう)
class

This is the verb version of the particle. You can make an example list of verbs among a possible larger list by conjugating each verb into the past tense and adding . At the end, you need to attach the verb する. Just like the particle, the tense is determined by the last verb, which in this case will always be する (since you have to attach it at the end). You can also use this with the state-of-being to say that you are a number of things at various random times among a larger list. Similar to regular verbs, you just take the noun or adjective for each state-of-being and conjugate it to the past state-of-being and then attach . Then finally, attach する at the end.

Rules for stating a list of verbs among a larger list using ~たりする

For verbs: Conjugate each verb to the past tense and add . Finally, add する at the very end.

Example

食べ、飲 → 食べ、飲んだ → 食べた、飲んだ → 食べたり、飲んだりする

For state-of-being: Conjugate the noun or adjective for each state-of-being to the past tense and add . Finally, add する at the very end.

Example

簡単、難し → 簡単だった、難しかった → 簡単だった、難しかった → 簡単だったり、難しかったりする

  1. 映画を見たり、本を読んだり昼寝したりする。
    I do things like (among other things) watch movies, read books, and take naps.

  2. この大学の授業は簡単だったり難しかったりする。
    Class of this college is sometimes easy, sometimes difficult (and other times something else maybe).

As you can see, the tense and negative/positive state is controlled by the last する.

  1. 映画を見たり、本を読んだりした
    I did things like (among other things) watch movies, and read books.

  2. 映画を見たり、本を読んだりしない
    I don’t do things like (among other things) watch movies, and read books.

  3. 映画を見たり、本を読んだりしなかった
    I didn’t do things like (among other things) watch movies, and read books.
