About
The character 瘤, representing a tumor or swelling, is structured with the illness radical 疒 combined with the phonetic element 留, which not only guides pronunciation but also conveys a semantic nuance of something retained or lingering. Etymologically, it originally described any abnormal lump or growth on the body, but its meaning gradually specialized to refer more precisely to neoplastic masses as medical knowledge developed. This shift from a general term for swellings to a specific pathological designation illustrates how the character's conceptual focus evolved while its graphical composition, consistently pairing disease with persistence, remained unchanged to reflect the condition's enduring and invasive nature.
