Urban Futurist DemocratI assumed the "quarter" in "quartermaster" referred to quarters in the sense of lodgings, which quartermasters often have some responsibility over in addition to rations and supplies, but apparently it's from an older use of "quarter" meaning the four quarters of the night the officer would organize watches for. #EtymologyOfTheDay
No one knows exactly how the word "sedan" came into being. #EtymologyOfTheDay
I read a post about the word "dinner" originally meaning "breakfast" and went deeper.
It's from Latin de + ieiunare, where ieiunare means to fast, so the same semantics as "breakfast".
Also, the adjective ieiunus is the ancestor of "jejune", through the sense-transition of abstinent => meager => unsatisfying, puerile (at the last step possibly confused with juvenile).
