Correct spelling, explanation: forty-six is a cardinal number. Its spelling may seem quite odd due to the fact that the spelling of 4 (four) and 14 (fourteen) is different. This form lacks the long vowel, which has a historical explanation. You can’t write it as fourty-six.

Definition of forty-six:
numeral, being one more than forty-five in number
My husband just turned forty-six and he’s planning a birthday party.
Forty-six people lined up at the entrance.

Incorrect spelling, explanation: fourty is a form that has been removed from the English language. We now spell this number as forty – with the short vowel – which is similar to fifty. It’s different from the way we spell the number 4 (four) and 14 (fourteen). Therefore, fourty-six is an incorrect version and the correct one is forty-six.
