Etymology Origin:
The word backpack emerged in the early 20th century, combining "back" (indicating placement) and "pack" (a container for carrying items). It reflects the practical design of a bag worn on the back, evolving from earlier terms like knapsack (German Knappen, "to eat" + Sack, "bag"). The simplicity of its structure—literal and functional—makes it easily recognizable across cultures.
