What does “Auld Lang Syne” mean? Originally written in a language called Scots, which is an ancient twist on English barely recognizable to modern-day English speakers, the phrase literally translates to “old long since,” but has adopted a more fluid definition along the lines of “for old time’s sake” or “the olden days.”
