When you speak French, you do not separate each word, you group them together, linking them. You pronounce a word group as you would a very long word: this is called a rhythmic group.
If a word ends in a consonant that is pronounced, and the next word starts with a vowel, you link the two together:
Relooking_avec Fabrice
Mon nouvel_appartement
Cuisine_américaine
Il_habite à Paris
The rhythmic group is a word group pronounced in a single breath. A rhythmic group is usually associated with an idea.
