Other Day (The)
.The day before yesterday. The Old English other was used for second, as in Latin, unus, alter, tertius; or proximus, alter, tertius. Starting from to-day, and going backwards, yesterday was the proximus ab illo; the day before yesterday was the altera ab illo, or the other day; and the day preceding that was tertius ab illo, or three days ago. Used to express “a short time ago.”
