Question

Where do we use preposition d' in french

Answer 1

Before a vowel like- je mange d'oeuf.- I eat an egg

Answer 2

The preposition is :

de

It becomes d' when we remove the 'e'.

We remove the e when we write it before a word beginning with a vowel or a word beginning with h.

h in French is treated as a vowel.

This can be shown in the example below :

Terre d'homme.
