Etymology

The word "daydream" is a compound formed from "day" (Old English dæg, meaning the period of daylight) and "dream" (Old English drēam, originally meaning joy or music, later evolving to denote mental imagery during sleep or idle fancy). The term emerged in the early 19th century to describe waking fantasies, blending the literal "day" with the imaginative connotation of "dream." This reflects a shift from nocturnal dreams to conscious, leisurely musings.
