(n, adj-f) person (usu. female) with an unhealthy romantic obsession (has a connotation of mental instability)
(chiefly Japanese fiction) A character, usually a girl, who has an obsessive and possessive side in regards to their crush, ready to use violent (if not murderous) means to maintain an exclusive bond.
A portmanteau of 病んでる (yanderu), contraction of 病んでいる (yande iru), progressive tense of 病む (yamu, “to be sick”), and デレデレ (dere-dere, “in a lovey-dovey, infatuated, or lovestruck manner”, adverb).
Developed on the model of tsundere (“being cold and even hostile towards another person before gradually showing a warm and caring side over time”).
