気をつけるところ

13~19はteen

12までは固有の単語ですが、13から19は「数字+teen」の形になります。

ただし、13(thirteen)と15(fifteen)は元の形(three、five)とは異なる点に注意が必要です。

0の読み方

0の読み方は3種類あります。

  1. zero
  2. oh(オー)
  3. nought(ノート)

「oh」は主に十の位の0や、電話番号・部屋番号など、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.西暦:1902[nineteen oh two]
例.電話番号:090[oh nine oh]
例.部屋番号:102[one oh two]

「nought」は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]

例.A million is a 1 with 6 noughts after it.
例.「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桁の数字で末尾が0でない場合、間にハイフン(-)を入れるのが正しい表記です。

例:77[✔ seventy-seven]
例:77×seventy seven]

40のつづりに注意

4は four、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。

例:40[✔ forty]
例:40×fourty]

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、という決まりがあります。

この項では百の位の数を英語でどう読むかについて解説していきます。

主な数字の例

数字読み方
100a/one hundred
101a/one hundred (and) one
110a/one hundred (and) ten
111a/one hundred (and) eleven
199a/one hundred (and) ninety-nine
200two hundred
999nine hundred (and) ninety-nine

※a/oneは a と one どちらも可の意。
※(and)は省略可。

気をつけるところ

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。

例:500[✔ five hundred]
例:500×five hundreds]

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 の前に数字は来ません。

hundred の後に and と言うべきか

イギリス英語では and を入れますが、アメリカ英語では and を入れません。

イギリス英語では two hundred ten は「210」という1つの数字ですが、アメリカ英語では「200と10」という2つの数字を表します。

英米どちらの英語のルールを使うかは本人の好みでかまわないと思いますが、気まぐれに and を入れたり略したりするのは混乱の元になるのでやめましょう。

a hundred か one hundred か

日常会話では基本的に a hundred と言い、one hundred は明確に他と区別したいときや、銀行業務等で数字の正確さを第一にしたい場面で使われます。

なお、a は数字の頭にのみ使えます。1,100などのように百の位より上の位がある場合は a hundred は使えません。

例:1,100[ a thousand one hundred]
例:1,100 one thousand one hundred]
例:1,100× a thousand a hundred]
例:1,100
×one thousand a hundred]

1,000~9,999

この項では千の位の数を英語でどう読むかについて解説していきます。

主な数字の例

数字読み方
1,000a/one thousand
1,001a/one thousand (and) one
1,099a/one thousand (and) ninety-nine
1,100a/one thousand one hundred / eleven hundred
1,101a/one thousand one hundred (and) one / eleven hundred (and) one
1,199a/one thousand one hundred (and) ninety-nine / eleven hundred (and) ninety-nine
2,000two thousand
9,999nine thousand nine hundred (and) ninety-nine

※a/oneは a と one どちらも可の意。
※(and)は省略可。

気をつけるところ

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。

例:5,000[✔ five thousand]
例:5,000×five thousands]

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ください。この場合 thousands の前に数字は来ません。

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、千の位の数字の直後に百の位の数字がある場合は and は入れません。これは英米の違いとは無関係であり、and を入れるのは明確に誤りです。

ただし、1,001や2,050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

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

基本は a thousand と言い、正確さを期する場合や千より上の位がある場合は one thousand と言います。

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、この言い方は基本的に1,999までです。2,000以上での使用例は多くありません。

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)。

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。

なお、余談ですが、数字の区切りにコンマではなくピリオドやアポストロフィ、スペースを使う国もあります。

ピリオドは主にドイツ、イタリア、スペインなどのヨーロッパ圏、スペースは主にフランス、カナダ、ロシアなどで用いられているようです。

10,000~999,999

この項では、英語で「万」をどう言い表すかについて解説していきます。

数字読み方

010,099ten thousand (and) ninety-nine
010,100ten thousand one hundred
010,999ten thousand nine hundred (and) ninety-nine

100,099one hundred thousand (and) ninety-nine
100,100one hundred thousand one hundred
100,999one hundred thousand nine hundred (and) ninety-nine
101,000one hundred (and) one thousand
109,999one hundred (and) nine thousand nine hundred (and) ninety-nine
110,000one hundred (and) ten thousand
999,999nine hundred (and) ninety-nine thousand nine hundred (and) ninety-nine

気をつけるところ

英語に「万」はない

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。

日本人が慣れるのはかなり時間のかかるところです。普段から独り言でブツブツと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ありません。

とにかく1万=10千、10万=100千です。頑張りましょう。

1,000,000~9,999,999

数字読み方
1,000,000one million

1,010,000one million ten thousand

1,100,000one million one hundred thousand
9,999,999nine million nine hundred (and) ninety-nine thousand nine hundred (and) ninety-nine

気をつけるところ

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、1億、1兆

ここまで来ると実用性の点で重要度が下がりますので、各桁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。

せっかくなので調べてみました。10の右肩にある数字は0の数を表します。たとえば100万は1,000,000なので106となります。
