Correct spelling, explanation: seventeen is the correct spelling of the number 17 in English. It follows the standard pattern for numbers in the teen range (thirteen, fourteen, fifteen, etc.). The word seventen is incorrect because it does not follow English spelling rules and does not exist in the language. While seven is the base number, when forming numbers from 13 to 19, English uses the -teen suffix rather than -ten.

Definition of seventeen:
Number, one more than sixteen, or seven more than ten
Emily celebrated her seventeenth birthday with a big party and lots of friends.
There are seventeen apples in the basket, enough for everyone to have one.

Incorrect spelling, explanation: even though seventen might seem logical (because it means seven and ten), it doesn’t match the established linguistic pattern in English. Language isn’t always logical – it’s shaped by historical usage, irregularities, and even accidents of history. Seventeen follows the traditional English pattern of forming teen numbers (thirteen, fourteen, etc.), which comes from Old English. The -teen ending originates from the Old English -tīene, which meant ten more than.
