Я разучился ежедневность

Qing, something is wrong with your example. Whether a word is missing or ... can't even guess.

Ordinarily, разучился requires a verb after it. )

I know Tatiana, разучиться делать что, but the author creates this :P

That's totally ungrammatical, apart from being nonsensical.)

Could you give some more context?

From the book Мбобо, which I often cited and asked the questions in this forum. )

I guessed this somehow.)
