ichidan verb, intransitive verb
fester; become inflamed and discharge pus
Rare term; describes a wound or sore that festers and oozes pus. More common alternatives include 化膿する (かのうする) or simply うむ.
傷口が膿み爛れて、ひどい状態だ。
The wound has festered and is in a terrible state.
Kanji spelling using 爛れる; rare and literary. The 膿み part is sometimes written in kana as うみ.
Mixed kanji-kana spelling; slightly more common than the full kanji form but still rare.
Compound of 膿み (umi, 'pus') + 爛れる (tadareru, 'to become inflamed/sore'). The exact historical derivation is uncertain, but the word is formed from native Japanese elements.
