Etymology

The term "seven-day" is a straightforward compound adjective formed by combining "seven" (from Old English seofon, ultimately Proto-Germanic sebun) and "day" (from Old English dæg, Proto-Germanic dagaz). It directly describes a duration or attribute spanning seven days, often used in contexts like "seven-day forecast" or "seven-day trial." The compounding follows typical English patterns for time-related terms (e.g., "two-week," "month-long").
