- Anandamide, the endogenous cannabanoid neurotransmitter; name comes from “the Sanskrit word ananda, which means ‘joy, bliss, delight.'” (I guess Vishy Anand, the chess player, gets his family name from this word too!)
- Coprolalia, the word for clinical profanity. Coprolalia comes from the Greek κόπρος (kopros) meaning “feces” and λαλιά (lalia) from lalein, “to talk”. Literally means to talk shit.
- Orthodoxy means “true/correct belief” (a normative claim, really, which makes it really interesting that sects of some religions are described as Orthodox). Relatedly: Orthogonal, meaning of right angles, comes from the same “ortho” root meaning correct. That means that “right” angles more generally means “true” or “correct” angles!
