Answer:
Je --> J'
Step-by-step explanation:
The letter H is always silent in French, yet there are two different types: H must, which acts like a vowel. H aspiré, which acts like a consonant.
Let's say your word is habite.
So instead of Je habite it would be J'habite
This is because e and h are vowels and vowels do not usually go together in French, so it's replaced with an apostrophe
