quixotic: [18] Quixotic commemorates Don Quixote, the hero of Cervantes’s novel of the same name (published in two parts in 1605 and 1615). He was a slightly dotty Spanish gentleman whose head became turned by tales of chivalric derring-do, which he sought to emulate in real life. His most famous exploit was to charge with his lance at windmills, under the mistaken impression that they were giants.
quixotic (adj.)
"extravagantly chivalrous," 1791, from Don Quixote, romantic, impractical hero of Cervantes' satirical novel "Don Quixote de la Mancha" (1605; English translation by 1620). His name literally means "thigh," also "a cuisse" (a piece of armor for the thigh), in Modern Spanish quijote, from Latin coxa "hip." Related: Quixotical; quixotically.
