Le jour d'après / Le jour d'avant
These can only be used on their own, and will mean the same as le lendemain and la veille, although they're a bit less elegant, more used in speech.
what is meant by "these can only be used on their own"? thank you
Le jour suivant / Le jour précédent Le jour suivant, Ali Baba retourna à la grotte.On the following day, Ali Baba returned to the cave.Le jour précédent, ils avaient quitté leur vieil appartement.On the previous day, they'd left their old flat.As for le jour suivant (on the following day) and le jour précédent (on the previous day), they are used in a past context just like le lendemain and la veille, but always on their own.
