ⵌ 1 ﹕ in deltarune, theres a darkner you can encounter in chapter 4, called Bibliox ! They have a proofread ACT, and in those you have to choose between misspelled words to find the correct spelling. The words used are very interesting.. iirc four of those words are a soundtrack in the deltarune OST! So the other words used in their ACT could be future song titles :3
