Incorrect spelling, explanation: this word may be challenging for English learners because this is the exception to a rule. Creating numbers from 11-19, we generally add the suffix teen to the numbers 1-9. However, the word fifteen is the exception. Therefore, fiveteen is incorrect.

Correct spelling, explanation: in Old English, there was the word fif representing the number five that we commonly use nowadays. Although the number 5 has currently a different form, the number 15 is nearly unchanged. Thus, exclusively fifteen is the correct form.

Definition of fifteen:
the symbol for the number 15 that means one more than fourteen,
I have already read fifteen episodes of this novel.
“What time is it?” “It’s seven fifteen.”

Phrases with fifteen:
famous for fifteen minutes – someone is famous for fifteen minutes when he enjoys a brief period of fame and celebrity,
