What does sennight mean?
Sennight is an archaic English noun denoting the night immediately following a particular day. In older writing, it could identify an evening or night by reference to the day just mentioned: “by the sennight” means “by the following night.” The word is not normally used to mean an unspecified period of darkness, despite its modern appearance, and it should not be confused with sevennight, an older term for a week or seven-day period. Today sennight is chiefly literary, historical, or deliberately antiquarian, so a writer using it may create an impression of age, formality, or traditional narrative style. Although dictionaries may record a plural form, the word is so rare in contemporary English that its use is more often recognizable as a historical expression than as part of everyday vocabulary.

Where does sennight come from?
Sennight comes from Old English sænniht, a compound referring to the next or following night. Its first element is historically related to the sense of “soon,” while niht means “night.” The expression survived into Middle and Early Modern English but gradually became obsolete as more direct phrases such as “the next night” came to dominate ordinary usage.
