About

堰 is a phono-semantic compound character meaning a weir, low dam, or embankment built across a river to manage or divert water flow. The semantic radical 土 (tǔ, earth) on the left indicates its construction from soil or mud. The phonetic component 匽 (yǎn) on the right provides the pronunciation and may subtly suggest the idea of covering or blocking, aligning with the function of impeding water. Its core meaning relates to water management and irrigation infrastructure, referring to earthworks that control water levels without completely halting the river's flow.
