all the livelong day
The whole day. "Livelong" comes from the Middle English phrase "leve longe." My hands hurt after sewing all the livelong day. I need a break after watching these kids all the livelong day.
all the livelong day
all day long. Well, of course you get to feeling stiff, sitting in front of a computer all the livelong day. I'd go crazy if I had to stay at home all the livelong day.
