Etymology

The word "four-hour" is a straightforward compound adjective formed by combining "four," derived from Old English "fēower" (meaning the number 4), and "hour," from Old French "hore" and Latin "hora" (meaning a unit of time). The compound logically describes a duration of four hours, retaining the original meanings of both morphemes.
