Accepted Answer

Bonjour Samuel,
In French it happens that words are “joined” when they are written (and therefore spoken) because of something called ‘elision’. Here is a link explaining it in more details: elision
At other times, you can have words being linked when spoken (but not when written) because of something called ‘liaison’. Here is a link about it: liaison
It is all about the hiatus or avoiding the hiatus. Basically, it is making sure the sequence of words sounds more pleasing to the ear, like in English with ‘an + vowel’ (an appartment) for example.
I hope this is helpful.
Bonne journée!
