この動詞の注意点

覚えておきたい3つの基本形：think – thought – thought。 → 不規則動詞
単語リストより： I think that …は「〜と思う」。進行形のI am thinking about itは「検討中です」という意味です。thは舌先を軽く歯にあてて発音し、「シンク」（sink）と区別しましょう。

太字と下線は語尾です。◆は規則から外れる形の印です。

日本語話者が間違えやすい点

誤り How do you think about this plan?
正しい What do you think about this plan?
「どう思う？」の「どう」をhowにしがちですが、思っている中身をたずねるのでwhatです。howを使うならHow do you feel about …?になります。

よくある間違い

誤り I sink so.

正しい I think so.

初めてthを発音すると、舌を歯の間に出すのが大げさに感じられます。そのため多くの人が「サ」「ザ」行で代用し、別の単語を言ってしまいます。thinkの代わりにsink（沈む）、threeの代わりにtree（木）、mouth（口）の代わりにmouse（ネズミ）。遠慮せず大げさにやってください。はっきりしすぎたthはだれにでも通じますが、「サ」では通じないことがあります。

子音：th、w、v、h、r

よく一緒に使う言葉

think twice — よく考え直す
think of doing something — 〜しようかと考える
think ahead — 先のことを考える

まぎらわしい動詞

feel feelは気持ちや感覚、thinkは頭で考えた意見や判断です。
