One to twelve in English are: one, two, three, four, five, six, seven, eight, nine, ten, eleven, and twelve. A simple pattern applies to the numbers from thirteen to nineteen. They are formed by adding "teen" to the base word, resulting in: thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, and nineteen. For numbers that end in zero, such as twenty, thirty, forty, fifty, sixty, seventy, eighty, and ninety, they are written with "-ty" as the suffix: twenty, thirty, forty, fifty, sixty, seventy, eighty, and ninety. Numbers from twenty-one to ninety-nine are formed by combining the English words for the tens place (from two to nine) with the ones place (from one to nine), separated by a hyphen. For example: twenty-one (21), thirty-two (32), forty-three (43), fifty-four (54), sixty-five (65), seventy-six (76), eighty-seven (87), and ninety-eight (98). One hundred is a special case and is written as "one hundred".
