revive, to rise again, collect
穌 centers on bringing something back to life or gathering scattered things together. The idea of revival connects to collecting what was dispersed and restoring it.
穌 combines 魚 (fish) and 禾 (grain), but the exact historical development is uncertain. It may have originally expressed reviving or gathering through these two elements, though the connection is not clearly established.
Picture a fish 魚 beside a grain stalk 禾. After a flood scatters fish and grain, someone collects them together and revives the stored food supply.
For ソ, imagine sewing a torn net to collect the scattered fish and grain: sew -> ソ, and the mended net helps revive the harvest.
