In the reading explanation for 後で, there is an explanation for the meaning:
"You can differentiate this one from 後ろ because it has a で at the end. Day (で) follows night which follows after day again. Automatically. "
The “automatically” part involves the reading, but the rest could be given in the meaning section. Since the meaning section is basically empty, I spent some time thinking of my own mnemonic to to remember the correct meaning, only to find it was already covered. If nothing else, at least indicate that the way to get the correct meaning is in the reading section.
