ないとう」は I don't think … English Moves the Not Forward

Negation

ないとう」は I don't think he'll come. です。日本語ろのしますが、の think のほうへげます。I think he won't come. も文法にはちますが、さがわってしまいます。ただし hope や wish はげません。

"I don't think he'll come" is how English says it. Many languages negate the second verb; English lifts the not forward onto think. "I think he won't come" is grammatical, but it shifts the weight of what you're saying. Hope and wish are the ones that refuse to play along.

るが、うのは

The Umbrella Moves Up but Covers the Back

I don't think he'll come. でしているのは、は「う」ではありません。ってはいるのです。されているのは「る」ほう。かっているのに、実際っているのはろのです。このげは think / believe / suppose / expect / imagine できます。れるまでえますが、ではこれがです。

In "I don't think he'll come," what's being denied isn't the thinking. You are thinking, quite definitely. What's denied is his coming. The umbrella hangs on the first verb while covering the second clause. This lifting is standard with think, believe, suppose, expect, and imagine. It looks odd until you're used to it, and then it becomes the natural shape.

げるのが Lifting is the default

I don't think this is the なぜ the なのか つにまる】 top・right・whole・next・same のように、がそれつにるので the。ろにするい。 right room.

ここ、部屋うとう。

しているのは「しい部屋だ」のほう。 What's denied is this being the right room.

I don't believe she said that.

がそんなことをったとはえない。

believe でもげがきる。 Believe lifts the negative the same way.

I hope it doesn't rain tomorrow.

明日らないといいな。

hope はげない。ろのる。 Hope doesn't lift. The negative stays in the second clause.

げる(think / believe / suppose / expect)

へ。これが The negative moves onto the first verb. This is the default order.

I don't suppose they'll notice.

づかれはしないとう。

げない(hope / wish)

ろのいたまま。かすとになる。 The negative stays in the second clause. Moving it up sounds wrong.

I hope you're not too tired.

れすぎていないといいけれど。

よくある Common Mistake

I think he won't come to the party.

はパーティーにないとう。(のつもりで)

I don't think he'll come to the party.

はパーティーにないとう。

文法としてはりではありませんが、きがずれます。I think he won't come. は「ないだろう」とんでいることをしたで、さがります。に「ないとう」とえたいでは、げます。このいは、日本語の「ないとう」と「ないだろうとっている」のい。think / believe / suppose / expect ではまずげる、とえておけばしません。

This isn't ungrammatical, but it lands differently. "I think he won't come" foregrounds a prediction and carries more conviction. When you simply mean that you doubt he'll be there, English speakers lift the negative forward. The gap is roughly the one between doubting something and predicting against it. With think, believe, suppose, and expect, lift by default and you'll be right.

  • I don't think so. そうはわない げの。I think not. はく、ではまず使わない。 The set lifted form. "I think not" is stiff and rare in everyday speech.
  • I don't suppose you could ...? 〜していただけないでしょうか げを使ったりやすくしてたりをめる。 A polite request built on the lift. It leaves the door open for a no.
  • not that I know of りではない けてするしている。 Denies while limiting the claim to what you personally know.
  • I doubt it. どうかな/たぶんうと doubt っているので not はらない。 Doubt carries the negative inside it, so no not is needed.
