adj .
romantic or idealistic to a foolish or impractical degree 어리석거나 비현실적일 정도로 낭만주의적이거나 이상주의적인

• The word quixotic is derived from the name of Don Quixote, the protagonist of Miguel de Cervantes's classic seventeenth-century novel. Don Quixote had read so many romances about the golden age of chivalry that he set out to become a knight himself and have chivalrous adventures. Instead, his romantic idealism almost invariably got him into trouble. To be quixotic is to be as foolish or impractical as Don Quixote in pursuing an ideal.
