What does de in french but in english?

Answer 1

"de" means "of" or " 's ", expressing a relationship.

For instance, "le chat de Paul" (Paul's cat) or "la ville de Paris" (the city of Paris)

It is spelled " d' " when followed by a word starting with a vowel ("d'Anne").

Same meaning if followed by a definitive article like "le" or "la" (the), but the spelling is different for a male noun: "le chat du voisin" (the neighbor's cat).
