A fortnight is a period of two weeks, or fourteen days. It is still commonly used in British English.
From Old English “feowertyne niht” meaning “fourteen nights.” Over time, the phrase squeezed together into a single word.
Fortnight literally hides ‘fourteen nights’ inside it, a reminder of when people counted time by nights, not days. Even though the word feels old‑fashioned, it still quietly lives on in schedules, rent agreements, and even video game names.
