0~99に関する注意点

文頭に数字は用いない

これは0~99に限った話ではありませんが、英文を書く際、文頭が数字になる場合は何ケタであろうと単語で書く、というのが書き方の決まりです。

0の読み方は3種類

0はzero以外にoh、noughtとも読まれます。

oh[オー]

数を数える場合は言いませんが、電話番号など、識別のために割り当てられた番号などを読む際によく言います。

例:
電話番号:090[oh nine oh]
部屋番号:102[one oh two]

nought[ノート]:普通名詞として(イギリス英語)

主にイギリス英語で0をnoughtと読む場合があります。

例:
0.25[nought point two five]

A million is a 1 with 6 noughts after it.
「100万は1の後に0が6個続く。」

21以上はハイフンを入れる

21以上の2ケタの数字で末尾が1~9の場合、間にハイフン(-)を入れるのが正しい表記とされています。

例:77[seventy-seven][×seventy seven]

40のつづりに注意

14はfourteenですが、40はfortyです。uがないことに注意しましょう。

英語の四則演算の読み方
1+1=2や1×1=1などの式を英語で言えますか?足し算、引き算、掛け算、割り算(四則演算)の基本的な英語表現をまとめました。

100~999

数字読み方 ※(and)は省略可
100one hundred
101one hundred (and) one
110one hundred (and) ten
111one hundred (and) eleven
199one hundred (and) ninety-nine
200two hundred
999nine hundred (and) ninety-nine

100~999に関する注意点

hundred は複数形にしない

200以降でもhundredは複数形にはならず、two hundred、three hundredとなっていきます。

ただし、hundreds of ~「数百の~;何百もの~」という表現はありますので注意して下さい。この場合hundredsの前には何も数字は来ません。

hundred の後に and と言うべきか

イギリス英語とアメリカ英語の違いです。

andを読むのはイギリス英語で、アメリカ英語では普通省略します。

日本ではアメリカ(北米)英語を中心に学習していますので、andは省略してかまいません。

a hundred か one hundred か

普段の会話ではa hundredのほうが普通です。one hundredは場合によってはかなり不自然に響くことがあります。

ただし、one hundredと言っておけば間違って伝わることはありませんので、非ネイティブの人はone hundredで問題ありません(基本的に流暢さよりも伝達力を第一に考えましょう)。

※1,000~9,999の項目で詳しく書いているが、one hundredは良いがa hundredは使えないという場合もあるので、慣れないうちはとにかくone hundredと言っておくほうが安全。留学などで周囲にネイティブだらけの状況になったら、彼らがいつa hundredを使うか観察し、それに合わせるのが一番お勧めの方法である。

1,000~9,999に関する注意点

thousand は複数形にしない

hundredと同じくthousandも複数形にはならず、two thousand、three thousandとなっていきます。

ただし、これもhundredと同じですが、thousands of ~「数千の~;何千もの~」という表現はありますので注意して下さい。この場合thousandsの前には何も数字は来ません。

thousand の後に and と言うべきか

上の表中の1,100や9,999などのように、千の位の直後に百の位がある場合andは不要です。これは英米の違いとは無関係で、常にそうです。

ただし、1,001や1,099など、百の位がとばされる場合、イギリス英語ではandが入ります。

a thousand か one thousand か

基本的に上のa hundredかone hundredかで書いた説明がそのまま当てはまります。

ただし、新しい注意点があります。

1,100の場合、千の位はone thousandでもa thousandでも大丈夫ですが、百の位はa hundredとは言えずone hundredのみ可能です。

これは2,101や39,120などでも同じで、千の位の数字の直後にある百の位が1である場合はone hundredとしか言えないことに注意しましょう。

thousand を使わない場合もある

4ケタの数であってもthousandを使わず、2ケタ+hundredで表す言い方もあります。

これは、たとえば1,100をeleven hundred、1,200をtwelve hundredと言うということです(末尾は00でなくてもかまいません)。

ただし、これはほとんどの場合1,999までで、2,000以上で使われることはまれです(末尾が00のときのみ使うという人もいるようですが)。

※aかoneかの議論と同じく、非ネイティブは常にthousandを使うことをお勧めする。周囲に多くのネイティブがいる状況なら、彼らの言葉をよく聞いて真似すると良いだろう。

thousand の後にコンマは必要か

4ケタ以上の数を数字で表す場合、1,100などのようにコンマが打たれるのが普通です。

人によっては単語で書く場合も同じ場所にコンマを打ち、one thousand, one hundredとすることもあります(末尾が000でない場合のみ)。

ただし、これは完全に好みの問題なので、書かなくても特に問題はありません。

10,000~999,999に関する注意点

英語に万はない

改めて言うことでもないかもしれませんが、英語に「万」の概念は存在しません。

代わりにten thousandとone hundred thousand、すなわち「10千」と「100千」を使います。

もちろん、日本人がすぐに慣れるのは難しい部分です。頭の中で何度も繰り返し反復練習する以外、反射的に英語が出るようになる方法はないでしょう。

一つのコツとしては、コンマをthousandだと思って読むことです。頑張りましょう。

10,000~999,999に関する注意点

millionはthousandと同じ用法

だいぶ数が大きくなりましたが、million以降は英語の言い方に新しい変化はありません。

two million、three millionとなってもmillionは複数形にはなりませんが、millions of ~「数百万の~・何百万の」という表現ははあります。

上の表を見ればわかりますが、直後にthousandの部分が来る場合は英米ともにandは不要です。ただし、一気に十の位や一の位にとぶ場合はイギリス英語ではandを入れます。

1,000万~1兆

ここまで来ると実用性という意味で重要度が下がりますので、各ケタの名称のみを示します。小さい数字が続く場合のルールはone million以前と同じです。
