Etymology

The word "daytime" is a straightforward compound of "day" (from Old English dæg, meaning the 24-hour cycle or the light portion of it) and "time" (from Old English tīma, meaning a measurable period). The combination logically refers to the illuminated portion of the day, contrasting with nighttime. This transparent structure reflects English's tendency to create descriptive compounds for clarity.
