Verb sequences
In this section, we'll learn how to describe verbs that happen after, before, and at the same time as another verb. To describe clauses that happen sequentially, we must first learn all the te-form conjugation rules.
Te-form conjugation rules
For the progressive tense, we only needed to learn the conjugation rules for plain verbs. However, nouns, adjectives, and the negative form can also be conjugated to the te-form.
- Plain nouns and na-adjectives: Attach 「で」 to the noun or na-adjective.
Examples- 学生+で = 学生で
- 暇+で = 暇で
- きれい+で = きれいで
- I-adjectives and negative: Replace the last 「い」 with 「くて」.
Examples- かわい
い+くて = かわいくて - 学生じゃな
い+くて = 学生じゃなくて - 食べな
い+くて = 食べなくて
- かわい
- Exceptions: As usual 「いい」 conjugates from 「よい」
- いい → よ
い+くて = よくて - かっこいい → かっこよ
い+くて = かっこよくて
- いい → よ
Sequence of actions
The te-form we learned at the beginning of this chapter is very versatile and has many uses. In fact, the te-form alone is used to express a sequence of actions that happen one after another. This will make your conversations smoother as it allows you to connect multiple sentences instead of having many smaller, separate sentences that are often too short.
- 朝 【あさ】- morning
- 起きる 【お・きる】(ru-verb) - to get up; to happen
- そして - and then
- 朝ご飯 【やさ・ご・はん】- breakfast
- 朝、起きた。そして、朝ご飯を食べた。そして、学校に行った。
Morning, (I) woke up. Then (I) ate breakfast. Then, (I) went to school. - 朝、起きて、朝ご飯を食べて、学校に行った。
Morning, (I) woke up, ate breakfast, and went to school.
Example
- 優しい 【やさ・しい】(i-adj) - gentle
- 頭 【あたま】 - head
- 人気 【にん・き】 - popularity
- どうする - what should one do (lit: how do)
- 飲み会 【の・み・かい】 - drinking party
- 彼女は、きれいで、優しくて、頭もいいから、皆に人気がある。
Because she is pretty, gentle, and smart, (she's) popular with everybody. - 宿題をしなくて、どうするんだよ?
(You) don't do homework and what are you going to do? - 飲み会は、今日じゃなくて、明日です。
Drinking party is not today, it's tomorrow.
Before and after
You can use 「前」 and 「後」 to describe an action as happening before or after another action.
- 前 【まえ】 - front; before
- 後 【あと】 - after
Example
- 寝る 【ね・る】(ru-verb) - to sleep
- 風呂 【ふ・ろ】 - bath
- 入る 【はい・る】(u-verb) - to enter
- ここ - here
- 来る 【く・る】(exception) - to come
- ちゃんと - properly
- 連絡 【れん・らく】 - contact
- する 【す・る】(exception) - to do
- 昼 【ひる】 - afternoon
- ご飯 【ご・はん】 - rice; meal
- 昼ご飯 【ひる・ご・はん】 - lunch
- 食べる 【た・べる】(ru-verb) - to eat
- 宿題 【しゅく・だい】 - homework
- 泳ぐ 【およ・ぐ】(u-verb) - to swim
- 危ない 【あぶ・ない】(i-adj) - dangerous
- 寝る前に、お風呂に入る。
Take a bath before going to sleep. - ここに来る前に、ちゃんと連絡したよ。
(I) properly contacted (you) before (I) came here. - 昼ご飯を食べた後、宿題をした。
Did homework after eating lunch. - 食べた後、泳ぐのは危ないです。
Swim after eating is dangerous.
Note: Be careful of the tense of the verb that comes before 「前」 and 「後」. 「前」 is non-past while 「後」 is always past tense.
Another way to describe an action is to use the te-form with 「から」. While similar to 「後」, 「~てから」 conveys a stronger and more immediate relation between the two events, often used for situations where the previous action needs to be completed for the next action to start.
Example
- 晩ご飯 【ばん・ご・はん】 - dinner
- 習う 【なら・う】(u-verb) - to learn
- いい (i-adj) - good
- 晩ご飯を食べてから、宿題をするよ。
(I'll) do homework after (I) eat dinner. - カタカナは、ひらがなを習ってから習うのがいい。
As for Katakana, (it) is good to learn after learning Hiragana
Two simultaneous actions
You can express two actions that are taking place simultaneously by attaching 「ながら」 to the end of the stem of the first verb. The tense is determined by the main verb at the end.
- Change the first verb to the stem and append 「ながら」
- 食べ
る→ 食べ+ながら → 食べながら - 遊
ぶ→ 遊び+ながら → 遊びながら
- 食べ
Example
- 話す 【はな・す】 - to speak
- 行儀 【ぎょう・ぎ】 - manners
- 悪い 【わる・い】(i-adj) - bad
- 辞書 【じ・しょ】 - dictionary
- 使う 【つか・う】(u-verb) - to use
- 文章 【ぶん・しょう】 - sentence
- 書く 【か・く】(u-verb) - to write
- 通じる 【つう・じる】(ru-verb) - to go through, to get across
- テレビを見ながら、宿題をする。
Do homework while watching TV. - 食べながら話すのは行儀が悪い。
(It's) bad manners to speak while eating. - 辞書を使いながら、日本語の文章を書いたけど、全然通じなかった。
Wrote Japanese text while using dictionary but (it) didn't get across at all.

Yes it does mean swimming
Yes it does mean swimming after eating is dangerous.
食べた後、泳ぐのは危ないです.
There's not much to the sentence,
食べた後(たべたあと) means after eating
泳ぐのは(およぐのは) is the verb to swim+ の and the particle は, which takes it from the verb form to a noun that can be the focus of the sentence
危ないです(あぶないです) means is dangerous.
食べた後、泳ぐのは危ないです。 Doesn't this
食べた後、泳ぐのは危ないです。
Doesn't this say eating after swimming is dangerous? If not, can someone explain this to me more thoroughly?
No. It says the opposite.
No. It says the opposite. 食べた後 after eating 泳ぐのは swimming 危ないです is dangerous. So it is saying "Swimming after eating is dangerous".
「後」 is referring to the
「後」 is referring to the preceding verb, therefore 「食べた後」 means "after eating".
(I think the past tense form implies that this action happens before the other action takes place. I could be wrong, though.)
The whole sentence could be translated as "after eating, swimming is dangerous" or "swim(ming) after eating is dangerous".
I wonder, however, if you have to use the 「に」 particle after 「前」 as shown in the examples (「寝る前に、お風呂に入る。」). Would it be the same if you didn't use it? Can you use it with 「後」 as well? Would be nice if someone could explain it.
後 means "after", therefore
後 means "after", therefore 食べた後 means "after eating" (lit.: "after having eaten"). The clauses with 後 or 前 seem to come before the following clauses, quite similar to other conjunctions (から、けど、ので etc.)
I'm not a hundred per cent sure, though, that's just what it seems to me.
I've got a question to: When using 前, do you always have to write に at the end of the clause? Because this was done in both examples and none of the two examples with 後.
You're correct. A pretty much
You're correct.
A pretty much direct translation is: 'After having eaten, swimming is dangerous.'
In fact it's the opposite. It
In fact it's the opposite. It means "swimming after eating is dangerous". 食べた後, means "after eating".
Never mind, I think I figured
Never mind, I think I figured it out.
