A fortnight is a period of fourteen days, or two weeks. Related words are fortnights and fortnightly. The word fortnight comes from the Middle English word fourteniht, which is a contraction of the Old English term feowertyne niht. Feowertyne niht means fourteen nights, corresponding to the Old German custom of counting time in nights rather than in days. When the term fortnight was coined, there was a similar term that meant a period of seven days or one week, seofon niht, which was abbreviated to the word sennight. Interestingly, sennight has fallen out of favor while use of the word fortnight has remained strong in British English. Fortnight is not seen in American English.
