The word for today in french is 'Aujourd'hui'

In the Origins of the French language, the word for today was 'hui' but the people in the marketplace communicating with each other kept getting confused

Because 'hui' sounded like 'oui' for yes

So they kept saying are you saying yes or today!

Eventually the word evolved and quite literally the word is 'In the day of today'

Au (à+le) jour de hui
