schoolbag
🎒 书 (book) + 包 (bag/wrap) = book-bag
书 means book; 包 means bag or to wrap. Together 书包 literally reads as book-bag, the standard word for a student's schoolbag or satchel.
书 — hand 又 holding brush over 曰 (say/speak)
Originally a pictograph of a hand gripping a writing brush above a mouth or vessel, depicting the act of writing speech down. The traditional form 書 shows 聿 (brush) over 曰 (to say). Simplified 书 preserves the brush-in-hand shape, and the meaning extended from 'to write' to 'writing' and then 'book'.
包 — 勹 wrap + 巳 fetus
包 is a pictograph showing a fetus (巳) wrapped inside a womb (勹, an enclosing shape). The original sense was 'to wrap' or 'enclose,' and it later extended to mean a bundle, package, or bag. It also serves as a phonetic component in many characters like 抱, 泡, and 饱.
