Tips

usage

疽 is a classical medical term referring to a deep-seated abscess or carbuncle. In traditional Chinese medicine, 痈疽 (yōng jū) describes surface versus deep suppurative infections. Rarely used in modern speech outside medical or historical contexts.

Components

radical

疒 nè

sickness (radical)

Sickness radical wraps the upper-left — pictograph of a person reclining on a sickbed — marks 疽 as a medical condition: a deep festering abscess or carbuncle in TCM terminology. Same radical drives 病 (illness), 痈 (carbuncle's near-pair), 疼 (ache), 癌 (cancer).

phonetic

且 qiě

moreover; and

且 supplies the sound — qiě → jū — through Old Chinese palatal-onset shift, the same shift that links 且 with 祖 (zǔ), 阻 (zǔ), 组 (zǔ). Visually distinctive: the rectangular grid of 且 makes 疽 easy to distinguish from neighboring disease chars like 疮 and 疚.
