The English Name for a Schoolbag
In the English language, a schoolbag is commonly referred to as a "backpack." This versatile item is essential for students of all ages, providing a convenient way to carry textbooks, notebooks, and other educational materials. Backpacks come in various designs, colors, and sizes to suit individual preferences and needs.
The term "backpack" is derived from the early 20thcentury French word "baccporte," which means "carry over the shoulder." Over time, the term has been adopted and adapted in Englishspeaking countries to describe a bag worn on the back. It is important to choose a backpack that is comfortable, wellpadded, and has enough storage space to accommodate all the necessary school supplies.
