bag是衣服还是文具？

Bag is commonly referred to as a schoolbag in English. As a noun, it is frequently used, yet the bag serves a specific purpose. Both clothing and schoolbags share a common thread: they are all nouns that can appear in sentences. People, too, are nouns, and therefore adding 's' to 'schoolbag' or 'clothing' can indicate the plural meaning, which is both a habit and an essential rule of the English language. Additionally, bags come in various shapes and sizes, each tailored to serve a specific function or purpose, from carrying books to storing items. This versatility makes them an indispensable part of everyday life, both in school and beyond.
