Ex. 東京に行く

= Toukyou ni iku

= to go to Tokyo

:rrrr: (negative)

東京に行かない

= Toukyou ni ikanai

= not to go to Tokyo

Now let’s add a question mark,.

東京に行かない

= Touyou ni ikanai?

It is not a negative sentence. It means,

“Do you want to go to Tokyo with me?”

“Why don’t we go Tokyo!” 

Note: Stress the last verb with rising intonation when you read it.

Polite form : You add “か  ( = ka) after ません ( = masen)

⬇️

東京に行きません

= Toukyou ni ikimasen ka?

= Would you like to go to Tokyo with me?

Note 1) Be careful with  か ( = ka).

A lot of people add “か ( = ka)” automatically when they ask a question.

It is totally acceptable adding か ( = ka) after ます ( = masu), ません ( = masen)

*ます ( = masu) +か ( = ka) →OK! 👍

*ません ( = masen) +か ( = ka)→OK!👍

But if you add か ( = ka)  after ない ( = nai)

 ⬇️

東京に行かない?!

= Toukyou ni ikanaika?

⚠️This is male speech and sounds rough.

Note 2 ) If you add の ( = no) after ない ( = nai) you can express a feeling of surprise.

Ex. 東京に行かないの?

= Toukyou ni ikanaino?

= Don’t you go to Tokyo?

polite form ないのですか  =  nai no desu ka?)

Ex. 東京に行かないのです

= Toukyou ni ikanai no desu ka?

OK, I will give you more examples with “ない  ( = nai)?

⬇️

Asking someone to do something together or encouraging someone to do something.

Ex. 一緒にお昼食べない

= Issho ni ohiru tabenai?

Do you want to eat lunch with me? (Why don’t we eat lunch together? )

Ex. この本、読まない

= Kono hon, yomanai?

= Do you want to read this book? (Why don’t you read this book?)

Ex. 明日、映画でも観に行かない

= Ashita, eiga demo mini ikanai?

= Do you like to go see a movie or something tomorrow?

Ex. 夏休み、私とニューヨークに行かない

= Natsuyasumi, watashi to nyuuyooku ni ikanai?

= Would you like to go to N.Y. with me over the summer vacation?

Ex. 日本語を勉強してみない

= Nihongo wo benkyou shite minai?

= Would you like to give studying Japanese a try?

Ex. 一緒にお茶でも飲まない

= Issho ni ocha demo nomanai?

= Would you like to have a cup of tea (or coffee) with me?

(This is a typical pick-up line and お茶  ( = ocha) doesn’t necessarily mean “a cup of tea.” It means to go to a coffee shop and have something to drink.)

Ex. 健一君も日本語能力試験を受けてみない

= Kenichi kun mo nihongo nouryoku shiken wo ukete minai?

= Do you also want to try to take the JLPT test, Kenichi?

Also, you use ~ない ( = nai)?」 for a tag question.

🔸noun : ~ではない ( = dewa nai)

:rrrr: 本ではない ( = hon dewa nai) It’s not a book/books

Go check じゃない ( = janai) lesson

  1. Hello Maggie-Sensei,

    Me again! (シ_ _)シ

    In your lesson, I see we use the は particle for な-adjectives to make them negative: ~ではない but not for い-adjectives: 〜くない

    But I’ve seen this: 安くはない. What is the difference between 安くない and 安くはない?

    And does it work too for な-adjectives? Like きれいはではない?

    Thank you so much, I wanted you to know by the way that your website is a huge boost in motivating me to learn Japanese.

    1. Hello again Gaspatcher,
      You add は either when you show the contrast or emphasize what come after.

      安くない→安くはない
      1) showing the contrast: Maybe it has a good quality but not cheap 2) Emphasizing the fact something is cheap.

      For na-adjective or noun,
      →きれいではない
      →私のものではない

      I’m so grateful to hear my site motivates you to learn Japanese. Yay! 😄

      1. Thanks Sensei for this explanation. I understand the difference now with 安くない and 安くはない.

        Sorry, I’m very pernickety (that’s my default) but what is the difference then with 安くはない (showing contrast) and それほど安くない? From my knowledge, それほど〜 tends also to show some contrast (it’s not that cheap).

        And can we mix up both and have それほど安くはない – what would that mean then?

        どうも有り難う先生

        1. おはよう Gaspatcher
          それほど安くはない/安くない It was not that cheap.
          Yes, you can use それほど and は together. Actually it is a very common pattern.
          But as you said since それほど already adds the emphasis, you can omit は as well.

  2. Hello 先生! Could you help me with the following sentence (from my textbook)?

    ジロジロ見ないの!

    To me, it seems like an imperative: “Don’t stare!” Am I correct? Also, is this female speech? Thanks!

    1. Hi Davide,

      That’s の has a function of emphasis and this form is often used when teachers or parents tell small children to do/not to do something as an imperative form.
      It is possible for men (teacher/father) to use this form but you are right, women tend to use it more than men.

      FYI, you also use の at the end of the sentence to make your point.

      だから、後でやるって言ってるの! I am telling you that I am going to do that later! (this speech pattern is for children or women)

  3. 先生、高校生の女の子とか若い人々の言い方は大人と違うですか?映画とかドラマに違って見えるけど。違うとどうやってdifferenciate できるかな?

  4. Hello ! I just finished reading your lesson and saw a mistake right here :
    ” 寝る(=okiru) to sleep
    寝ない (=okinai) not to sleep ”
    Isn’t it “neru” and “nenai” ?

    And by the way, about that part :
    “明日、映画でも観に行かない?”
    Just wondering, is there any difference between 見に行く and 観に行く ? I’ve always learnt to write it like the first one, so I was a bit surprised !

    Thank you for what you do, I love your lessons, there’re really great !
    頑張ってね!

      こんにちは、サーフィー!
      Ooops!! Thank you for spotting the mistakes. I fixed them. (I copied and pasted them with my little paws and forgot to changed them. ^;ェ;^,)

      As for 見る vs 観る
      Basically you can use 見る
      But we use 観る for movies, musicals, arts, plays, arts, something you appreciate, sightseeing, etc.
