Etymology

The word "all-night" is a straightforward compound formed by combining "all" (from Old English eall, meaning "entire" or "whole") and "night" (from Old English niht, referring to the dark period between sunset and sunrise). The compound emerged in Modern English to describe events or durations spanning the entire night, reflecting a practical and transparent construction.
