Correct spelling, explanation: the number forty had already appeared in Germanic languages and then in Old English. However, it was in Middle English when the word started to look similar to the modern version as it had the form fourti. It is worth noticing that the letter -u has disappeared from the word over the centuries and today the correct form is forty.
Definition of forty:
1. number – the cardinal number that appears between thirty-nine and forty-one;
Next month Jack’s going to turn forty and we want to prepare a surprise party for him.

Incorrect spelling, explanation: one of the most common spelling mistakes in English is to write the cardinal number forty as
fourty. It is no wonder as the number four is actually spelled with the -u letter. As a result, even native speakers of English are surprised that forty lacks the -u letter.

English is a topic which is close to me. Many thanks!
