About
桫 is a phono-semantic compound: the radical 木 (wood) on the left indicates its botanical category, while the component 沙 (sand) on the right provides the pronunciation "suō" or "shā". This character appears almost exclusively in the botanical term "桫椤" (suōluó), meaning tree fern. As it is confined to this specific taxonomic term, 桫 has no independent meaning in standard vocabulary and conveys sense only within its compound form.
