Need help with this sentence
In one of the stories, there was this sentence: "Un selfie est une photo que l'on prend de soi-même"
I know what it means, but I don't get the l' part. What does the l' refer to?
The l' is added for euphony. It sounds bad to have que and on together, because "on" starts with a vowel right after a vowel. You could also put "qu'on" but "que l'on" is quite common.
