About
The character "滤", meaning to filter, is a phono-semantic compound formed by the water radical on the left, indicating its association with liquids, and the component "虑" on the right, which primarily offers phonetic guidance while also suggesting a conceptual link to the act of careful examination or sifting. Its traditional form, "濾", maintains this identical structure but employs the traditional version of the phonetic element. Over its historical usage, the character has retained its core meaning pertaining to the physical removal of impurities from fluids, yet it has also acquired extended metaphorical uses in contexts like filtering information or refining ideas, demonstrating a subtle semantic broadening while staying grounded in its original compositional logic.
