How to say "fifteen" in Japanese
Choosing the right word

- nounA katakana borrowing of the English word, covering the same sense of fifteen; being less common than 十五, it is seldom the word you actually want for the number.
For the number fifteen in ordinary use, 十五 is the common choice; 「フィフティーン」 is a katakana borrowing of the English word that you will only occasionally meet, so it is rarely the word a learner needs.
