I’m not quite sure what I’m doing wrong here?

Hey :bowing_man:

It should be 忘れちゃった instead of 忘れてちゃった。
The て form is used, but て itself is removed and ちゃう is attached to what is left from it.

It goes like this:

わすれるーmake て form→忘れてーremove て→忘れーadd ちゃう→忘れちゃうーpast form→忘れちゃった

The structure section was a bit unclear, so I have fixed it:

I hope it helps!
Cheers :+1:

Ah that explains what went wrong, thank you so much! All the examples used てしまう as well, so it got quite confusing :sweat_smile: Maybe have some examples alter readings in this case, or maybe alter readings at random even :open_mouth:
