to wrap
🎁 tsu-tsu-mu: tuck, tuck, and it's wrapped — 包 is also the kanji for package
包 began as a character for a baby enclosed in the womb: something fully covered on all sides. The same kanji appears in 小包 (kozutsumi, parcel) and 包装 (housou, packaging), so the wrap meaning carries across words.
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.
