Etymology
The compound "all-day" combines the Old English word "all" (meaning "entire" or "whole") with "day" (from Old English "dæg," referring to a 24-hour period). It emerged in Modern English to describe something that spans the entirety of a day, such as an event or service. The morphemes retain their original meanings, making the compound transparent and easily interpretable.
