Doing my spaced repetition of some of the content in the course I came across this sentense from lesson 4.3:
Avez-vous un numéro de téléphone où l'on peut vous joindre ?
Doing another lesson about pronouns I was wondering if the l' in front of on was a pronoun for téléphone.
Wondering about this, I asked chatGPT about it and it told me that the l' is mainly inserted to make it easier to pronounce, because où on has to vowels. Meaning the où ends with a vowel and the on starts with one.
It also told me that this is used more in formal and written french and that it's not as commen in every day spoken french.
Does anybody know about this?
