The building blocks
English number words are built from a small set of parts. The ones from one to nine, the irregular teens from eleven to nineteen, and the tens — twenty, thirty, forty, fifty, sixty, seventy, eighty and ninety — combine to cover the whole range. To name any two-digit number you take the tens word and attach the ones word with a hyphen: twenty-one, forty-five, ninety-nine. The only numbers without a hyphen are the round tens themselves and the teens, which already have single names.
Watch the spellings that trip people up: forty has no “u” (never fourty), and ninety keeps the “e” from nine. The teens hide two oddities too — eleven and twelve look nothing like their digits, and thirteen and fifteen shorten three and five.

Spelling tips that save you
- Always hyphenate 21–99:
seventy-three, not “seventy three”. fortyhas no u;ninetykeeps the e.- Don’t add “and” inside numbers under 100 — that’s only used after hundreds in British style.
- One hundred is two words; there is no hyphen between “one” and “hundred”.
