CJK Unified Ideograph-7A5E

It means grain that grows wild or from dropped seed.

The word names rice first, then more broadly grain or plants that return without deliberate sowing. The related forms 穭 and 稆 carry the same lexical sense; 稆生 is the established compound for self-sown growth.

The exact glyph 穞 is not a headword in Shuowen. Its earliest clear dictionary relative here is 秜, defined as rice that falls one year and grows the next. Later dictionaries connect 穭 and 稆 with 旅; the related graph 旅 is much older, with oracle-bone and late Shang and early Western Zhou bronze attestations, but those early records do not prove the agricultural sense.

Why did people write this word?

They wrote it to name self-sown grain in farming texts.

That distinction mattered when a crop returned from fallen seed and when food had to be gathered outside planned fields. The Hou Han chronicle records officials collecting self-growing grain during wartime hunger, and its commentary glosses the character as self-growing.

This history does not point to a one-time inventor, ritual emblem, or secret code. It shows a practical agricultural label that moved among 穞, 穭, 稆, 秜, and the loan graph 旅.
