Etymology

The word "yesterday" originates from Old English geostran dæg, combining geostran (meaning "of yesterday" or "previous") and dæg (meaning "day"). The morpheme "yester-" survives in archaic or poetic terms like "yesteryear" and reflects a Germanic root (gester-) for temporal proximity. Over time, the spelling simplified to "yesterday," retaining its core meaning of "the day before today."
