Borrowed from Japanese ヤンデレ (yandere), a portmanteau of 病んでる (yanderu), contraction of 病んでいる (yandeiru), progressive tense of 病む (yamu, “to be sick”), and デレデレ (dere-dere, “to become lovey-dovey, infatuated, lovestruck”).
Developed on the model of tsundere (“being cold and even hostile towards another person before gradually showing a warm and caring side over time”).

- Looking at anime charts, there's always the harem series with the dense hero and a bunch of girls whose personalities are pulled out of a set cast of tropes (the Childhood Friend, Tsundere, Yandere, and Lolita, for instance).
- 2014, Olivia D. Knight, Please, Let Me Be a Seiyuu!, BookRix, →ISBN, page unnumbered:
- “Believe it, man. In fact, she's seriously creepy. Like creepier than that pink-haired girl from Future Diary.”
“Wait, what?” Sam got that reference quickly, but was not happy with the comparison. She wasn't a psychopathic, murderous Yandere stalker, from what he could see.
