1. Day and day of the week
What day of the week is it?
The word for “day” in Japanese is ひ 「hi」 and the Japanese prefix ひ「hi」with よう「yō」 to create “day of the week”. However when the よう 「yō」and ひ「hi」is combined, the first letter for the word “day” changes and becomes び「bi」.
So the resulting word for “day of the week” is ようび 「yōbi」.
The change in sound when combining certain words together is called euphonic change.
