Meaning & readings

run alongside, follow along, run along, lie along

On’yomi エン
Kun’yomi そ.う、-ぞ.い

Origin

This character combines the water radical on the left, which marks it as related to water or flowing, with a sound hint on the right that suggests the pronunciation. The idea of water running or flowing alongside something naturally led to the meaning of "running along" or "following alongside." Think of how a river runs along the edge of land—the water element captures that sense of following a path or boundary. Over time, the character extended to mean anything that goes alongside or follows along, whether water or not.
