What Is the ない Form of Verbs?
The suffix 〜ない functions similarly to "not" in English, as in 食べない (not eat), 飲まない (not drink) and 来ない (not come). Also known as the ない form, this is the negative plain form of verbs. So when used at the end of a sentence, it makes the sentence casual. It can also be used in the middle of a sentence, in which case it doesn't usually show whether the sentence is polite or not, but simply gives information about whatever comes next.

ない Form for the Present
Just like the る form of verbs, the ない form of verbs is used to talk about both the present and the future. If we use it in the present, it is usually to talk about a situation or a "general truth" rather than a habitual action (we tend to use 〜ていない to talk about habits). So if we're watching our favorite Japanese TV show without subtitles, we might lament our inability to follow along by saying:
- I don't understand at all.
Similarly, if we can understand the Japanese just fine, but find the show to be meaningless, we can say:
- Watching it is pointless!
That said, we can use ない for habits if the emphasis is on the permanence of the situation, rather than the action:
- I don't watch TV much.
In speaking, 〜ない is often combined with particles to add a particular nuance or to give a more conversational tone:
- It makes no sense, huh?
ない Form for the Future
We can also use this form to talk about things we won't do. This can refer to the very near future, like a party tonight:
- I'm not going to the party tonight.
It can also be used to talk about our intentions for the more distant future:
- There's no way I'm ever going back to where I come from!
ない Form for Invitations
You may have already learned the polite way to make invitations using 〜ませんか. We can use the ない form in the same way, to make casual invitations. Simply adding the question particle か to the ない form is one way to do this:
- How about we go together next time?
However, this has an assertive feel to it so is not very common in everyday conversations. Rather, as so often happens in casual Japanese, we simply use the ない form as it is and rely on intonation to make it clear that we are asking a question:
- How about we go together next time?
ない Form in the Middle of Sentences
Just like other plain forms, 〜ない can be used in the middle of a sentence. In this case, it no longer makes the sentence casual because politeness is generally shown at the end of a sentence.
Plenty of structures in Japanese only work when paired up with some kind of plain form. For this, the ない form will come in very handy. For example, かもしれない (probably) and と思う (I think) can both be used only with the plain form. So if we want to say we probably won't go to a party tomorrow, we can use かもしれない or its polite form かもしれません:
- I probably won't go to the party tomorrow.
Although the overall sentence above is polite, and so has the polite form at the end, using the polite form before かもしれません would be incorrect:
ない Form with Nouns
The ない form also behaves like other plain forms in the way it fits together with nouns. If we want to say "an interesting TV show" we can put simply put おもしろい before 番組 to give us おもしろい番組. To say "a place I go to," we simply say 行く場所. We can do exactly the same thing with verbs ending in 〜ない, too.
- a place I don't go to
- the person (or people) who isn't going
- the person (or people) who doesn't understand
In English, we need to put the additional information afterwards, and often a word like "who" or "that," but in Japanese we can simply add the extra information (in plain form) before the word. While this takes a little getting used to, it's a very handy way to make more complex sentences and you'll come across it in Japanese all the time.
Other Forms of ない
The beauty and strangeness of this form is that, even though the verbs that end in 〜ない keep their meanings as verbs, they basically "become" い-adjectives when it comes to conjugating them. Odd as it may seem at first, the fact that the form ends in 〜い makes this peculiarity very easy to remember.
So since ない conjugates just like an い-adjective, if you can conjugate standard い-adjectives, you can conjugate the ない form too! Take a look at the table below to see what we mean.
|Negative Form||食べない||食べないです||don't eat|
|Past Negative Form||食べなかった||食べなかったです||didn't eat|
|Conditional Negative Form||食べなければ||if don't eat|
