to leave behind
🧳 遗 leave-behind + 留 remain = what stays after someone is gone, handed down
留 — 卯 (top) + 田 (field)
Originally a phono-semantic compound: 田 (field) suggests staying on the land, with 卯 hinting at the sound. Over time it came to mean 'remain, stay, keep,' as in keeping someone on the land or holding something in place. Modern uses include 留学 (study abroad) and 保留 (retain).
