About
The character '龋', meaning dental caries, developed from its traditional form '齲' which combines the semantic radical '齒' for tooth with the phonetic component '禺' to suggest pronunciation. Its meaning has been consistently specific to tooth decay since early appearances in medical literature, showing no notable semantic shift. Over time, the character's structure experienced gradual modifications through conventional writing practices, resulting in the modern form where '齿' serves as the simplified semantic element and '禹' functions as the phonetic element, preserving the original etymological construction while reflecting changes in script usage.
